One test for Diabetes is called the A1C test. It measures the percentage of red blood cellsthat have sugar-coated hemoglobin attached to them (called the A1C score). Assume thatthe distribution of A1C scores is normally distributed with a mean of 5.0 and a standarddeviation of 0.5 (the actual mean and standard deviation are slightly above these valuesand are gender dependent. I have rounded to make calculations easier).Determine the probability of observing an A1C score greater than 6.06 i.e P(X > 6.06).Enter your answer to 4 decimal places.

Obtain the Z-score for the random variable X equals 6.06. The Z-score for the random variable X…

A sports dataset collected over ten years shows that the total number of baskets scored by an NBA player in a season depends on the amount of his yearly salary. The sample mean and standard deviation of salaries of studied players over this period are $1.1 million dolars and $0.4 million dollars, respectively. The sample mean and standard deviation of total number of scored baskets in a season are 701.7 and 57.1, respectively. The correlation coefficient between the yearly salary and the number of baskets is 0.75. Based on this data, fit a linear regression model and predict the total number of baskets that will be scored in a season by an NBA player with salary $3.9 million dollars a year. Write your answer as an integer, by rounding your solution to the nearest integer. Number of baskets in a season:
Women are recommended to consume 1730 calories per day. You suspect that the average calorie intake is different for women at your college. The data for the 16 women who participated in the study is shown below: 1764, 1612, 1772, 1405, 1685, 1634, 1823, 1770, 1691, 1762, 1485, 1883, 1834, 1578, 1733, 1885 Assuming that the distribution is normal, what can be concluded at the a = 0.10 level of significance? a. For this study, we should use E-test for a population mean b. The null and alternative hypotheses would be: Ho: ?v|| Select an answer v H.: ?vSelect an answer v c. The test statistic ? (please show your answer to 4 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is f. Based on this, we should fail to reject g. Thus, the final conclusion is that. O The data suggest that the population mean calorie intake for women at your college is not significantly different from 1730 at a = 0.10, so there is not enough evidence to conclude that the…
The Army reports that the distribution of head circumferences among male soldiers is approximately normal with μ =22.8 inches and σ = 1.1 inches. What is the circumference of a soldier whose head is 2.34 standard deviations above the mean?
The acidity of liquids is measured by pH on a scale of 0 to 14. Distilled water has pH 7.0, and lower pH values indicate acidity. Normal rain is somewhat acidic, so "acid rain" is sometimes defined as rainfall with a pH below 5.0.The pH of rain at one location varies among rainy days according to a Normal distribution with mean 5.75 and standard deviations 0.50. What us probability of acid rain
The level of nitrogen oxides (NOX) and nonmethane organic gas (NMOG) in the exhaust over the useful life (150,000150,000 miles of driving) of cars of a particular model varies Normally with mean 8080 mg/mi and standard deviation 66 mg/mi. A company has 1616 cars of this model in its fleet. Using Table A, find the level ?L such that the probability that the average NOX + NMOG level ?¯x¯ for the fleet greater than ?L is only 0.030.03 ? (Enter your answer rounded to three decimal places. If you are using CrunchIt, adjust the default precision under Preferences as necessary. See the instructional video on how to adjust precision settings.)

In nutrition, the recommended daily allowance of vitamins is a number set by the government as a guide to an individual's daily vitamin intake. Actually, vitamin needs vary drastically from person to person, but the needs are very closely approximated by a normal curve. To calculate the recommended daily allowance, the government first finds the average need for vitamins among people in the population, and the standard deviation. The recommended daily allowance is then defined as the mean plus 2.5 times the standard deviation. What is the recommended daily allowance for a vitamin with mean u and standard deviation o? recommended daily allowance =
