A simple random sample of size n=15 is drawn from a population that is normally distributed. The sample mean is found to be x=61 and the sample standard deviation is found to be s=10. Construct a 90​% confidence interval about the population mean.

Which expression is equivalent to the expression for the perimeter of the larger garden?

Arandom sample of 45 observations results in a sample mean of 68. the population standard deviation is known to be 23 a. compute the margin of error at a 959% confidence interval. b. compute the 95% confidence interval for the population mean c. compute the 90% confidence interval for the population mean. d. compute the 75% confidence interval for the population mean

What's the answer to this question 5x-15=-65
