A patient is classified as having gestational diabetes if their glucose level is above 144 milligrams per deciliter (mg/dl) one hour after a sugary drink is ingested. Rebecca's doctor is concerned that she may suffer from gestational diabetes. There is variation both in the actual glucose level and in the blood test that measures the level. Rebecca's measured glucose level one hour after ingesting the sugary drink varies according to the Normal distribution with µ= 146 mg/dl and o = 4 mg/dl. What is the probability of Rebecca being diagnosed with gestational diabetes if her glucose level is measured: (a) 4 times CS Scanned with CamScanner
Cholesterol levels for teenage boys can be modeled by a normal distribution with mean 150 mg/dl and standard deviation 25 mg/dl. About 0.15% of 14-year-old boys have cholesterol levels less than what value? Use the empirical rule and do not round your answer.

In a particular statistics exam, the 10th percentile of final exam score is 59, and the 90th percentile of final exam score is 93. A histogram of the scores approximately follows the normal curve. What is the approximate standard deviation of the final exam scores? Hints: What is the z value in the normal table that gives you closest to 80% of the area between -z and z? Now what does that tell you about the number of SDs in between 59 inches and 93 inches? You might find it helpful to draw a picture of the normal curve with original units and standard units. 13.1 26.2 17.2 6.5
The distribution of blood cholesterol level in the population of young men aged 20 to 34 years is close to Normal with standard deviation ? = 45 milligrams per deciliter (mg/dL). You measure the blood cholesterol of 13 cross-country runners. The mean level is x = 174 mg/dL. Assume that ? is the same as in the general population. How large a sample is needed to cut the margin-of-error in half for a 90% confidence interval of the mean level ? among the cross-country runners?

Calcium levels in people are normally distributed with a mean of 9.7 mgdL and a standard deviation of 0.5 mgdL . Individuals with calcium levels in the bottom 10% of the population are considered to have low calcium levels. Find the calcium level that is the borderline between low calcium levels and those not considered low. Carry your intermediate computations to at least four decimal places. Round your answer to one decimal place.
Student Satisfaction sent from average to the 60th percentile (z score = .2533). Dr. Reed wants to know the projected impact on test scores. All she knows is that Student Satisfaction and Student Test scores are correlated at .43 and the current average test score is 81% with a standard deviation of 5%. Show your work
Hemoglobin levels in adult males are normally distributed with a mean of 14.5 g/dL and a standard deviation of 0.6 g/dL. The normal hemoglobin range for men is 13.8 g/dL to 14.9 g/dL. What percentage of men have hemoglobin levels in the normal range? Round your answer to four decimal places. If we randomly collect samples of men with 19 in each sample, what percentage of those samples have a mean hemoglobin level that is within the normal range? Round your answer to four decimal places
Psychology students in the Izmir University of Economics completed the Dental Anxiety Scale questionnaire in 2020. In this study, scores on the scale range from 0 (no anxiety) to 20 (extreme anxiety). The mean score was 14 and the standard deviation was 3.5.
