Draw a normal curve with a mean of 60 and a standard deviation of 13. Describe how you constructed the curve and discuss its features. Choose the correct graph of the normal curve below. O A. В. OC. 34 47 60 73 86 30 45 60 75 90 47 60 73 86 99 Describe how you constructed the curve and discuss its features. The normal distribution curve is centered at and has 2 points of inflection, representing H-6, and representing µ+o. (Type integers or decimals.)

T and p value please

Use a table of cumulative areas under the normal curve to find the z-score that corresponds to the given cumulative area. 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. 0.051 Click to view page 1 of the table. Click to view page 2 of the table. The cumulative area corresponds to the z-score of (Round to three decimal places as needed.)

Fluorescent lightbulbs have lifetimes that are normally distributed with a mean of 6.2 years and a standard deviation of 1 year. The figure below shows the distribution of lifetimes of fluorescent lightbulbs. Calculate the shaded area under the curve.Express your answer in the decimal form accurately to at least two decimal places. Answer:

Assume that a randomly selected subject is given a bone density test. Those test scores are normally distributed with a mean of 0 and a standard deviation of 1. Draw a graph and find the probability of a bone density test score greater than -1.62. Sketch the region. Choose the correct graph below. O A. 1.62 Q The probability is (Round to four decimal places as needed.) OB. Q -1.62 -1.62 ♫ OD. Q -1.62 1.62 Ε

One graph in the figure represents a normal distribution with mean u= 15 and standard deviation o = 2. The other graph represents a normal distribution with mean u=11 and standard deviation o = 2. Determine which graph is which and explain how you know. A B 11 15 ... Choose the correct answer below. O A. Graph A has a mean of u = 15 and graph B has a mean of u = 11 because a larger mean shifts the graph to the right. O B. Graph A has a mean of u = 11 and graph B has a mean of u= 15 because a larger mean shifts the graph to the left. O C. Graph A has a mean of u = 11 and graph B has a mean of u = 15 because a larger mean shifts the graph to the right. O D. Graph A has a mean of u = 15 and graph B has a mean of u = 11 because a larger mean shifts the graph to the left.

I can’t figure out formula or answer for bone density

Assume that a randomly selected subject is given a bone density test. Those test scores are normally distributed with a mean of 0 and a standard deviation of 1. Draw a graph and find the probability of a bone density test score greater than - 1.89. Sketch the region. Choose the correct graph below. O A. OB. C. O D. 1,89 -1.89 -1.89 -1.89 1,89 The probability is (Round to four decimal places as needed.)

The mean is 146 and the standard deviation is 35. A score of 41 is how many z-scores below the mean?
