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.
