A company opening a new theater is interested in knowing the average price charge by the other movie theaters. A random sample of 100 movie theaters taken by the company showed a mean price of a movie ticket to be $6.75 with a standard deviation of of $.80
a) what is the point estimate of the mean price of movie tickets for all theaters
b) what is the margin of error associated with this estimate
c) construct a 99% confidence interval for the population mean µ Answer by ewatrrr(24785) (Show Source):
Hi
a) what is the point estimate of the mean price of movie tickets for all theaters $6.75
b) what is the margin of error associated with this estimate .8/10 = .08
c) construct a 99% confidence interval for the population mean µ
ME = 2.58(.08) = .21
CI: 6.75 -.21 < u < 6.75 + .21
($6.54, $6.96)
