Suppose you have a sample of 36 observations with the sample mean = 2 and the sample standard deviation = 7. Compute the t-statistic corresponding to these values for the null hypothesis that mean = 0. Test two-sided alternative hypothesis that mean 6= 0. Do you reject the null hypothesis at p = 0:05? At p = 0:01? If the sample size is reduced to 25, do you get the same conclusions?

Expert Solution

Since P-value = 0.0953 > 0.01, so we fail to reject H0 at 1% level of significance.

ii)

Since P-value = 0.1660 > 0.01, so we fail to reject H0 at 1% level of significance.

Suppose we are interested in the mean scores on an exam. A random sample of 36 scores is taken and gives a sample mean (sample mean score) of 68 (x̄ = 68). In this example, we have the unusual knowledge that the population standard deviation is 3 points. Do not count on knowing the population parameters outside of textbook examples. Find a 90% confidence interval for the true (population) mean of statistics exam scores.
