1.) What is the probability that any randomly selected student (male or female) had a high school GPA between 3.00 and 4.00? Solve this problem using the Standard Normal Table (Z table). Show all work and provide the probability as a decimal rounded to four decimal places.
2.) If a female student had a high school GPA of 4.00, what percentile would this be for all female students? Solve this problem using the Standard Normal Table (Z table). Show all work and provide the probability as a decimal rounded to four decimal places.

Suppose a researcher believes that the average height of female
students in a large local high school is 140 cm. The researcher
wants to construct an interval that contains the true average
height of all female students in the local high school with a
certain prespecified probability. The researcher selects 36 female
students at random from the high school. The distribution of
heights is known to follow a normal distribution.
