A random sample of 40 videos posted to youtube was selected. A month later, the number of times that each had been viewed was tabulated. The mean number of viewings was 242 with a sample standard deviation of 320. Find the upper bound of the 99% confidence interval for the mean number of times videos posted youtube have been viewed in the first month. Round to the nearest integer.

A botanist collected on leaf at random from each of 10
randomly selected mature maple trees of the same species. The mean
and the standard deviation of the surface areas for the 10 leaves
in the sample were computed. Assume the distribution of surface
areas of maple leaves is normal. What is the appropriate method for
constructing a one-sample confidence interval to estimate the
population mean surface area of the species of maple leaves, and
why is the method appropriate?...

A study of women’s weights found that a randomly selected sample of 150 women had a mean weight of 147.3 lb. Assuming that the population standard deviation is 19.6 lb., construct a 95% confidence interval estimate of the mean weight of all women. Choose the correct interval from below: Choose one • 10 points (144.211, 150.389) (140.611, 146.789) (144.667, 149.933) (144.163, 150.437)
