Question

You wish to test the claim that μ = 49 at a level of significance of α = 0.05 and are given sample statistics n = 5, = 51, and s = 15. Compute the value of the standardized test statistic, t. Round your answers to three decimal places.

Answer 1

Solution :

This is the two tailed test .

The null and alternative hypothesis is ,

H0 :   =45

Ha : 45

Test statistic = z

= ( - ) / s / n

= (51-49) / 15/ 5

Test statistic = 0.298
