For a normal distribution with = 21 and = 2.2, determine the z-score of 16.5494.

z-score= [three decimal accuracy]

9.For a standard normal distribution, determine P(-2.5 < z < 0.5).

P(-2.5 < z < 0.5)= three decimal accuracy

10. From a normal distribution with = 30 and = 3.8, samples of size 32 are chosen to create a sampling distribution. In the sampling distribution determine P(30.84 < x < 31.075).

P(30.84 < x < 31.075)= three decimal accurac
