The average American man consumes 9.5 grams of sodium each day. Suppose that the sodium consumption of American men is normally distributed with a standard deviation of 1 grams. Suppose an American man is randomly chosen. Let X = the amount of sodium consumed. Round all numeric answers to 4 decimal places where possible. a. What is the distribution of X? X ~ N( b. Find the probability that this American man consumes between 9.7 and 10.5 grams of sodium per day. c. The middle 20% of American men consume between what two weights of sodium? Low: High:

Assume that a randomly selected subject is given a bone density test. Bone density test scores are normally distributed with a mean of 0 and a standard deviation of 1. Draw a graph and find P12, the 12th percentile. This is the bone density score separating the bottom 12% from the top 88%. Which graph represents P12? Choose the correct graph below. P12 The bone density score corresponding to P12 is (Round to two decimal places as needed.) O B. P₁2 ✔ C O C. P12 O D. P12

the mean is 146, and standard deviation is 35. A score of 181 is how many z-scores above the mean?

Assume that adults have IQ scores that are normally distributed with a mean of u = 105 and a standard deviation o = 15. Find the probability that a randomly selected adult has an 1Q less than 129. Click to view page 1 of the table. Click to view page 2 of the table. The probability that a randomly selected adult has an IQ less than 129 is (Type an integer or decimal rounded to four decimal places as needed.)

Assume that the readings at freezing on a batch of thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. A single thermometer is randomly selected and tested. Find P26, the 26-percentile. This is the temperature reading separating the bottom 26% from the top 74%.P26 = °C(Round answer to three decimal places)

Assume that the readings at freezing on a batch of thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. A single thermometer is randomly selected and tested. Find P29, the 29-percentile. This is the temperature reading separating the bottom 29% from the top 71%.P29 = °C(Round answer to three decimal places)

Assume that the readings at freezing on a batch of thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. A single thermometer is randomly selected and tested. Find P80, the 80-percentile. This is the temperature reading separating the bottom 80% from the top 20%.P80 = °C

Assume that thermometer readings are normally distributed with a mean of 0degrees°C and a standard deviation of 1.00degrees°C. A thermometer is randomly selected and tested. (The given values are in Celsius​ degrees.)   Between -1.47and 1.76

Assume that adults have IQ scores that are normally distributed with a mean of u= 105 and a standard deviation o = 15.
