Answer 1

Answer #1

a)

p value = 0.0200

As p avlue > 0.01 fail to reject null hypothesis

b)

p value = 0.6235
As p avlue > 0.01 fail to reject null hypothesis

A random sample is selected from an approximately normal population with an unknown standard deviation. For each the given set of hypotheses, sample sizes and t-statistics, find the p-value, draw a t-curve and shade the region of which the area the p-value indicates. As it’s not possible to find the precise p-values using a t-table, it suffices to give a range. (a) HA : μ > 0.5, n=26, T =2.6 (b) HA : μ ≠ 0.5, n=26, T = 2.6...
