o test H0​: μ=40 versus H1​: μ<40​, a random sample of size n=25 is obtained from a population that is known to be normally distributed. If x=37.1 and s=14.8​, compute the test statistic of t0 and If the researcher decides to test this hypothesis at the α=0.1 level of​ significance, determine the critical​ value.
A random sample of 50 students was asked to estimate how much money they spent on textbooks in a year. The sample skewness of these amounts was found to be 0.83 and the sample kurtosis was 3.98. Test at the 10% level the null hypothesis that the population dis- tribution of amounts spent is normal.
Based on a random sample of 25 units of product X, the average weight is 102 lbs., andthe sample standard deviation is 10 lbs. We would like to decide if there is enough evidenceto establish that the average weight for the population of product X is greater than 100 lbs.Assume the population is normally distributed.what is the critical value to test the claim at (alpha)= ,01?
