**Understanding the Distribution of Pregnancy Lengths**The lengths of pregnancies in a small rural village are normally distributed with a mean of 270 days and a standard deviation of 14 days.**Finding the Middle 68% Range for Most Pregnancies:**To determine the range where you'd expect to find the middle 68% of most pregnancies, apply the empirical rule (68-95-99.7 rule), which states that approximately 68% of values lie within one standard deviation of the mean. Therefore, the range would be:- Mean ± 1 Standard Deviation- Calculations: 270 ± 14**Finding the Middle 68% Range for Sample Averages:**If you were to draw samples of size 49 from this population, and wanted to know the range where the middle 68% of most averages for the lengths of pregnancies in the sample fall, use the standard error. The standard error (SE) is given by the formula:- SE = Standard Deviation / √Sample Size- SE = 14 / √49 = 14 / 7 = 2Then, apply the same empirical rule for the sample means:- Mean ± 1 Standard Error- Calculations: 270 ± 2**Instructions for Input:**Enter your answers as numbers. Your answers should be accurate to one decimal place.

If your score on your next statistics test is converted to a z score, which of these z scores would you prefer: - 2.00, - 1.00, 0, 1.00, 2.00? Why? OA The z score of 1.00 is most preferable because it is 1.00 standard deviation above the mean and would correspond to an above average test score. O B. The z score of 0 is most preferable because it corresponds to a test score equal to the mean. OC. The z score of - 1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average test score. OD. The z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores. O E. The z score of -2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores.

There are two major tests of readiness for college, the ACT and the SAT. ACT scores are reported on a scale from 1 to 36. The distribution of ACT scores is approximately Normal, with mean of 21.9 and standard deviation of 5.8. SAT scores are reported on a scale from 400 to 1600. The distribution of SAT scores is approximately Normal, with mean of 1,059 and standard deviation of 203. What ACT scores make up the top 10% of all the scores? Round to the nearest whole number.

Suppose you have already calculated the mean, the average deviation, and the standard deviation of the weights in pounds of 20 third-graders. a. if these weights were converted to kilograms and the mean and the average deviation were once again calculated, would the second average deviation be (numerically) less than, greater than, or equal to the first average deviation? Explain your answer. b. If the standard deviation of these weights were calculated in kilograms, would it be (numerically) less than, greater than, or equal to the first standard deviation?
