1.13 unit test graphs of sinusoidial functions The function of f (x) is multiplied by a factor of 2 and then 3 is added to this function

Using the normal distribution principle, the Zscore which corresponds to the area under the normal curve at P(Z < z) = 0.9967 is 2.716

To obtain the Zscore in this scenario, which is the number of standard deviations from the mean value for a given score ; we make use of Zscore calculator or a normal distribution table ;

Using a normal distribution table;

Therefore, the Zscore value is 2.716
