Question

The standard deviation for a population is 60. A sample size of 120 is examined in the context of a statistical assessment. The mean for the sample is 1,350. The preferred level of statistical significance is 5%. The population has a mean of 1,500. The statistical argument made by the assessors is that the sample and the population are the same. Is this assertion accurate? Why, or why not? Use the correct steps in testing a hypothesis.

A sample of size 194, taken from a normally distributed
population whose standard deviation is known to be 9.50, has a
sample mean of 91.34. Suppose that we have adopted the null
hypothesis that the actual population mean is greater than or equal
to 93, that is, H0 is that μ ≥ 93 and we want to test the
alternative hypothesis, H1, that μ < 93, with level of
significance α = 0.05. a) What type of test would be...
