Question
Need help on the last part
The next step is Method.
Answer the four key questions to determine an appropriate method: the question type is hypothesis testing ✔✔, the study type is sample data, the
type of data is one numerical variable ✔ , and the number of samples is one. Given these answers, it makes sense to consider a one-sample t test
for a population mean.
Recall the test statistic for a one-sample t test, where the value of u in the test statistic is the hypothesized value from the null hypothesis, Ho: μ = 135.
