Find the percent of the total area under the standard normal curve between the following pair of z-scores. z= 0.65 and z = 1.1 In order to find the area between the area under the curve between the two z-scores, first find the area to the left of each z-score. The area to the left of z = 0.65 is The area to the left of z = 1.1 is next find the area between the area under the curve between two z-score.
Please answer number 4 and 5.
Given a standard normal distribution, find the normal curve area under the curve which lies to the left of z=1.43
Find the area in the right tail more extreme than z = 2.25 in a standard normal distribution. Round your answer to three decimal places. Area =
Please write clearly. Thank you.
Use the standard normal table to find the z-score that corresponds to the cumulative area 0.9195. If the area is not in the table, use the entry closest to the area. If the area is halfway between two entries, use the -score halfway between the corresponding 2-scores. Sick to view page 1 of the standard normal table.

Use the standard normal table to find the z-score that corresponds to the given percentile. If the area is not in the table, use the entry closest to the area. If the area is halfway between two entries, use the z-score halfway between the corresponding z-scores. If convenient, use technology to find the z-score.

Gentle Ben is a Morgan horse at a Colorado dude ranch. Over the past 8 weeks, a veterinarian took the following glucose readings from this horse (in mg/100 ml). 91 88 82 103 97 108 84 91 The sample mean is x ≈ 93.0. Let x be a random variable representing glucose readings taken from Gentle Ben. We may assume that x has a normal distribution, and we know from past experience that ? = 12.5. The mean glucose level for horses should be ? = 85 mg/100 ml.† Do these data indicate that Gentle Ben has an overall average glucose level higher than 85? Use ? = 0.05. (a) What is the level of significance? State the null and alternate hypotheses. Will you use a left-tailed, right-tailed, or two-tailed test? H0: ? = 85; H1: ? > 85; right-tailed H0: ? > 85; H1: ? = 85; right-tailed H0: ? = 85; H1: ? ≠ 85; two-tailed H0: ? = 85; H1: ? < 85; left-tailed (b) What sampling distribution will you use? Explain the rationale for your choice of sampling distribution.…
