In a test of the hypothesis Upper H 0 : mu equals 10 versus Upper H Subscript a Baseline : mu not equals 10 a sample of n=50 observations possessed mean x over=10.6 and standard deviation s=2.7. Find and interpret the​ p-value for this test.

Answer #1

Here population standard deviation (sigma) is unknown so we can use t-test.

Also, using ti-83 calculator.

therefore,

p-value (p) = 0.1225

In given information level of significance (alpha) is not available so, we can use alpha =0.05

Conclusion :

P-value is greater than alpha so we do not reject the null hypothesis (H0). Therefore, there is not sufficient evidence to support the claim.
