Assume that a sample is used to estimate a population mean . Use
the given confidence level and sample data to find the margin of
error. Assume that the sample is a simple random sample and the
population has a normal distribution. Round your answer to one more
decimal place than the sample standard deviation. (please show
work)

Degrees of freedom = n-1
= 51 - 1
= 50
t critical value at 0.05 significance level for 50 df is 2.009
Margin of error = t * S / sqrt(n)
= 2.009 * 202 / sqrt(51)
= 56.8
Margin of error = 56.8 (Rounded one more decimal places than sample standard deviation)

Assume that a sample is used to estimate a population mean μμ. Find the margin of error M.E. that corresponds to a sample of size 15 with a mean of 37.7 and a standard deviation of 16.5 at a confidence level of 99.9%. Report ME accurate to one decimal place because the sample statistics are presented with this accuracy. Do not round the answer.

Assume that a sample is used to estimate a population mean μ. Find the margin of error M.E. that corresponds to a sample of size 24 with a mean of 51.6 and a standard deviation of 10.5 at a confidence level of 99%. Report M.E. accurate to one decimal place because the sample statistics are presented with this accuracy. Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
