A scientist found that the lengths of a certain population of snakes can be reasonably described using a normal distribution with a mean of 42 cm and a standard deviation of 2 cm. If the scientist collected a sample of 89 snakes, how many of the snakes would be expected to have a length less than 40 cm? A 14 30 C 60 D 74
See picture for questions a and b. Problem For admission to graduate school, Diane is taking the physics subject-matter test, and Lena is taking the chemistry subject-matter test. For each of these tests, the distribution of scores is clearly bell-shaped. Scores for the physics test have a population mean of 631 points with a standard deviation of 26 points. Scores for the chemistry test have a population mean of 608 points with a standard deviation of 35 points. Diane scored 695 on the physics test, and Lena scored 667 on the chemistry test.

Select all true statements below (Multiple or none can be true). With a large, representative sample, the histogram of the sample data will follow the normal curve closely. If two lists of numbers have exactly the same average of 50 and SD of 10, then the percentage of entries between 40 and 60 must be exactly the same for both lists. Half of a list of numbers is always below its average. The median and average of a list of numbers are not necessarily close together.
D Question 24 The weights of cats is Normally Distributed. The mean weight is 10 lbs with a standard deviation of 0.2 lbs. Draw the normal curve and fill in the cut scores and percentages. Then answer the questions below: Based on a sample of 600 cats, how many would you expect to weigh more than 10.4 lbs? Based on a sample of 600 cats, how many would you expect to weigh at least 9.8 lbs. but not more than 10.2 lbs? Based on a sample of 600 cats, how many would you expect to weigh more than 10 lbs?
A distribution of numbers is given by the following frequency histogram. Which of the following would be true? a. The mean would be greater than the median O b. The median would be greater than the mean C. The standard deviation would be less than 1 O d. The mean would be greater than the standard deviation

Which of the following best describes the relationship between the computed mean and the actual mean? O A. The computed mean is close to the actual mean because the difference between the means is more than 5% of the actual mean. B. The computed mean is not close to the actual mean because the difference between the means is less than 5% of the actual mean. C. The computed mean is not close to the actual mean because the difference between the means is more than 5% of the actual mean. D. The computed mean is close to the actual mean because the difference between the means is less than 5% of the actual mean.
