Solving question 1 only as per Chegg policy,
We first calculate the t-stastic using the formula
t = (sample mean - hypothesized mean)/ sample standard error
the degree of freedoms, df is n-1
Now, when we have the degrees of freedom and the significance level, we look at the corresponding critical value from the table by looking at the correct row and column.
This critical value is now compared with the t stastic.
