Solution Summary

Calculates probability using Normal Probability Distribution.

I was wondering if someone could help explain the NormalDistribution to me, maybe in more simple terms. An example would also be useful. I am using the program Minitab to generate my answers to questions.

If x is normally distrubed with u = 20.0 and o = 4.0, determine the following:
a. P(x > 20.0)
b. P(16.0 < x < 24.0)
c. P(X < 12)
d. P(x = 22.0)
e. P(12.0 , x , 28.0)
f. P(x 15)

What are the characteristics of a standard normaldistribution? Can two distributions with the same mean and different standard distributions be considered normal? How might you determine if a distribution is normal from its graphical representation?

If np ≥ 5 and nq ≥ 5 estimate P (fewer than 2) with n= 13 and p= 0.4 by using the normaldistribution as an approximation to the binomial distribution if np < 5 or nq <5 then state that the normal approximation is not suitable.

In what ways is the t distribution similar to the standard normaldistribution?
In what ways is the t distribution different from the standard normaldistribution?
How does the formula for the t test differ from the formula for the z test?

h-p is said to be the leading seller of pc's in the U.S WITH 27% share of the pc market. if a researcher selects 130 recent pc purchases, use the normal approximation to the binomial to find the probability that more than 39 bought a h-p computer

For a sample size 16, the sampling distribution of the mean will be approximately normally distributed:
A. regardless of the shape of the population
B. if the shape of the population is symmetrical
C. if the sample standard deviation is known
D. if the sample is normally distributed
