What proportion of a normal distribution is located in the tail beyond z = 1.50?

Sketch the normal distribution with a. µ = -2 and σ = 2.b. µ = -2 and σ = 1/2.c. µ = 0 and σ = 2.

Find the value of za/2 when 1- a = .98. Explain your answer by using the standard normal curve.

A population forms a normal distribution with a meaning of 85 and a standard deviation of 24 compute the Z score for the sample mean M equals 914N equals 36 what is Z

Find Pas, that is find 90 percentile of z-score from the standard normal distribution. 6.

Exactly 95% of a normal distribution is located between z = +1.96 and z = -1.96. How much of the distribution is located in the tail beyond z = +1.96?

Sunscreens are products that protect the skin from skin cancer by preventing the sun's ultraviolet (UV) radiation from penetrating the skin. According to dermatologists, the recommended amount of sunscreen needed to cover the exposed areas of the body is at least an ounce. In a study conducted specifically for a group of women aged 21 to 30 years, it was found the amount of sunscreen (X) applied by the group follows the normal distribution with mean of 0.6 ounce and standard deviation of 0.25 ounce.   The amount of sunscreen applied by women aged 21 to 30 years follows a bell-shaped distribution which is symmetric at X = _____.
