Actually in this case we will make use of the z test
statistic. In which we calculate for the z score and then use the standard
normal distribution tables to find for the P value at the calculate z score.
z = (x – u) / s
z = (97 – 98) / 2
z = -0.5
The z value should be greater than 1.65 to for the null
hypothesis to be accepted. Hence rejected.
Check the picture below
now, the angle is degrees, thus, when getting the sine, make sure your calculator is in Degree mode
