Explanation:
Detailed explanation-1: -Alternate hypothesis (H1): The alternate hypothesis is always what is being claimed. “In our case, Tedd believes(Claims) that the actual value has changed”. He doesn’t know whether the average has gone up or down, but he believes that it has changed and is not 100 anymore.
Detailed explanation-2: -Our null hypothesis is that the mean is equal to x. A two-tailed test will test both if the mean is significantly greater than x and if the mean significantly less than x.
