A study was conducted to estimate the mean amount spent on birthday gifts for a typical family having two children. A sample of 120 was taken, and the mean amount spent was $195.37. Assuming a standard deviation equal to $37.87, find the 90% confidence interval for m, the mean for all such families (show all work).

Answer
Sample mean = 195.37
Standard deviation = 37.87
Standard error of mean = s / â n
Standard error of mean = 37.87 / â 120
SE = 37.87/10.9545
Standard error of mean 3.457
Confidence interval 195.37-(3.457)(1.655)
and 195.37+(3.457)(1.655)
90% (189.65, 201.09)

Note:
In your question, you have stated 'assuming a standard deviation of 37.87).
I have computed the confidence interval with sample mean 195.37 and sample standard deviation 37.87 which means you should use the t-distribution (rather than normal distribution) which has a value of 1.655.

If your standard deviation is the population standard deviation you would use 1.645 instead.
Assuming sigma (population standard deviation is known), here is another confidence interval.
Sample mean = 195.37
Standard deviation = 37.87
Standard error of mean = Ï / â n
Standard error of mean = 37.87 / â 120
SE = 37.87/10.9545
Standard error of mean 3.457
Confidence interval 195.37-(3.457)(1.645)
and 195.37+(3.457)(1.645)
90% confidence interval (189.68, 201.06)

The two intervals are more or less the same because of the large sample size.

In this pic the girl is totally working it:http://images.google.com/imgres?imgurl=http://s2.thisnext.com/media/230x230_no_border/vintage-burgundy-80s-leather_7135ABEE-Vintageous-yellow.jpg&imgrefurl=http://www.thisnext.com/item/3EA9292E/72D507D7/vintage-burgundy-80s-leather&usg=__3p3Cp2b1sAgPLqFZdKB5gnPvyRE=&h=191&w=230&sz=33&hl=en&start=10&um=1&tbnid=DYixq0pA0h0lfM:&tbnh=90&tbnw=108&prev=/images%3Fq%3Dburgundy%2Bleather%2Bjacket%26um%3D1%26hl%3Den%26rlz%3D1G1GGLQ_ENUS299%26sa%3DN

This year in fashion has been all about mixing-leathers, colors, metals, prints... So own your jacket! You could even mix in some colored scarves (keep the rest of you look simple-all black), like another answerer mentioned:orange!

Here's another look, a bit more funky vintage, but I love it: http://farm3.static.flickr.com/2361/2015931359_446b5b5273_b.jpg

My boyfriend and I have been dating for a month and a half officially now but have been basically together since the beginning of september. He's turning 18 on Sunday and i have no idea what to get him! He's big into basketball, and track, he also likes clothes a lot. My budget is around $90 since i didn't get him a big christmas present.

What should I serve at my 3 year old's princess birthday party?

Lynn C

I have invited 90 people, and there will be approximately 20 little kids. I plan to do pb&j, and also cucumber&cream cheese sandwiches cut into hearts and stars. I also was thinking chicken salad sandwiches for the adults. But other than that, I am not sure. I definitely need some variety, but I don't want to do only chicken salad, and have to make 60 of those. I'd rather do smaller groupings of several dishes.

Answer
You're ready... your princess has invited the belles of the ball to the finest Princess Birthday Party of the year. You've purchased decorations, planned a few games and have some lovely take home gifts for your guests. Now it's time to plan the finest menu for your royal princess and her court. Let's make it so fabulous that the girls will remember this day when they're planning their future daughter's parties and one that will make your princess throw her hands around your neck and say, "Oh mom! You're the best ever!"

What follows are 5 tips for you in creating the menu of the decade for your princess birthday party.

1. Keep it simple. The last thing you need on a busy day is for you to be running around like crazy trying to make cherries flambé or tiramisu with crème fraise. However, with a little creative planning, you can make something spectacular and still be able to take photos of the lovely girls eating your birthday dainties. There are SO many recipes available at your fingertips that are not only delicious but easy to make with items you probably have in the house or can pick up in your local grocery store at minimal cost (another key!). You can just punch a name of a recipe into your google search box and hundreds of recipes will pop up. Just keep it simple!

2. Presentation is everything. Think about it, mom. A peanut butter sandwich is nice, but, make that sandwich and cut it with petite cookie cutters into various princessly shapes and you have something spectacular. Even just cutting the sandwiches with a glass into a circle and then cutting the circles in half would work. Display them nicely on a glass plate with some red grapes or flowers and it's no longer just a boring sandwich but a delicacy that's a delight to look at AND eat.

3. Throw the "no sugar" rule out the window. Ok, I'll get hate mail for this one but c'mon mom! Your princess only has the bash of the century once a year, so break the rules a little and provide something sweet to eat. Balance it out with a lower sugar drink and other dainties that aren't sugar laden.

4. Make the drink pink! Pink lemonade, pink Kool-Aid, pink soda... anything pink in a clear plastic cup and you'll be the coolest mom on the block. Float a half of a strawberry in the cup and you may as well get a revolving door to your house. You'll be the hit of the neighborhood!

5. Work with a time line and schedule for the day of the party. A checklist of what you'll be serving and when you need to pull it out of the freezer or fridge, what goes where, etc., and how long each thing takes will insure that you won't forget any of the details and insure that you won't go to open the fridge for a late night snack after your princess is in dream land and see the strawberries that you meant to put in the royal goblets.
