Manny made 4 pizzas to share among himself and 6 friends how much pizza will each person get? well reread the question and ask yourself what is the question is asking you. this problem does not ask you to solve it. in fact, you have to put the number listed as a improper faction. it ask you how much pizza will each person get. if he have 6 friends including himself that means the denominator will be 7 and the numerator is 4. the answer will be 4/7. hope that explains to you all!

Arandom sample of 15 observations is used to estimate the population mean. the sample mean and the standard deviation are calculated as 172 and 63, respectively. assume that the population is normally distributed. a. with 99 confidence, what is the margin of error for the estimation of the population mean? b. construct the 99% confidence interval for the population mean. c. construct the 95% confidence interval for the population mean. d. construct the 83% confidence interval for the population mean. hint: you need to use excel function =t. inv.2t to find the value of t for the interval calculation.
