Question: (a) A statistician randomly sampled 100 observations and found X = 106 and s = 35. Calculate the t statistic and p value for testing.

(a) A statistician randomly sampled 100 observations and found X = 106 and s = 35. Calculate the t statistic and p value for testing. H0 : = 100 against HA : > 100. Carry out the test at the 1% level of significance. (b) Repeat part (a), with s = 25. (c) Repeat part (a), with s = 15. Repeat question 1 using HA : 100
