Consider the following hypothesis test:H0: = 18Ha: ≠ 18A sample of 48 provided a sample mean = 17 and a sample standard deviation s = 4.5.If requires, round your answers to two decimal places. Compute the value of the test statistic (to three decimal places.)

The value of the test statistic is -1.539 .

Step-by-step explanation:

We are given with the  following hypothesis test ;

                    : = 18

                    : 18

Also, we are provided a Sample mean, = 17 and a Sample standard deviation, s = 4.5.

The test statistics we will use here is;

                          ~

So, test statistics =   ~  { as n = sample size = 48 }

                            = -1.539 .

Therefore, the value of the test statistic is -1.539 .

i got 142 as my answer
