Peele is interested in the average price of an entree at a French restaurant, but only has a random sample of 9 prices (prices are not listed on the menu). Using this random sample, Key calculates that a 90% confidence interval for the true mean is given by (65, 88). (You can assume the prices follow a normal distribution). Use this information to do the following: a) Calculate 7. (Hint, what does a confidence interval look like?)
b) Calculate s.
c) Construct a 95% confidence interval for the true mean price of all the entrees, f.

4 packs of water and 7 packs of candy bars

step-by-step explanation:

35x4=140

140/20=7

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
