The body temperatures of adults have a mean of 98.6° F and a standard deviation of 0.60° F. If 36 adult- are randomly selected, find the probability that their mean body temperature is greater than 98.5° F. Hint: You will need to use the sampling distribution of the sample mean. 0.9360 0.0228 0.8413 0.8188

The size of fish is very important to commercial fishing. A study conducted in 2012 found the length of Atlantic cod caught in nets in Karlskrona to have a mean of 49.9 cm and a standard deviation of 3.74 cm. Assume the length of fish is normally distributed. A sample of 17 fish was taken. d) Find the mean of the sampling distribution of the sample mean.     Put the numeric value in the first box and the correct units in the second box.     e) Find the standard deviation of the sampling distribution of the sample mean.     Put the numeric value rounded to two decimal places in the first box and the correct units in the second box.    g) Find the probability that the sample mean length of the 17 randomly selected Atlantic cod is less than 51.5 cm.       Round final answer to 4 decimal places.      DO NOT use the rounded standard deviation from part e in this computation.      Use the EXACT value of the standard deviation with the square root.      h) Find the probability that the sample…

60% of all the students passed an exam. If a random sample of 10 students is selected, What is the mean and the standard deviation ?

Assume that the average weight of an NFL player is 245.7 lbs with a standard deviation of 34.5 lbs. The distribution of NFL weights is not normal. Suppose you took a random sample of 32 players. What is the probability that the sample average will be less than 260 lbs?

The height of Christmas trees are normally distributed. The standard deviation of Christmas trees is 200 inches and the mean height is 1400 inches. What is the probability that a randomly selected Christmas tree is between 1100 and 1438 inches?

A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 241.2-cm and a standard deviation of 0.6-cm.Find P22, which is the length separating the shortest 22% rods from the longest 78%.P22 =

The average heart rate for adults is 72 bpm with a standard deviation of 6bpm. The distribution of heart rates is Normal.  a. What is the probability that a randomly selected heart rate is less than 60 bpm? b. What is the probability that a randomly selected heart rate is between 70 and 80 bpm? c. What is the 40th percentile of heart rates?

Compute the standard deviation of the sampled proportions if p=.8 and n=50. Round to three places.

Assume that blood pressure readings are normally distributed with a mean of 122 and a standard deviation of 6.4. If 64 people are randomly selected, find the probability that their mean blood pressure will be less than 124.
