Lengths of human pregnancies have a bell-shaped distribution with mean 266 days and standard deviation 16 days. Based on the graph that is labeled through the use of the Empirical Rule, what percentage of human pregnancies last less than 234 days and what percentage of human pregnancies last more than 282 days?
Systolic blood pressure readings are normally distributed with a mean of 121 and standard deviation of 15. If a person from the population was selected at random, find the probability that their blood pressure is in the acceptable range (between 114 and 140) for an athletic activity. A. Label and shade the normal distribution curve to model this problem.
Samples are drawn from a population with mean 144 and standard deviation 43. Each sample has 12 randomly and independently chosen elements. Find the mean, uz, of the distribution of sample means.
Mean=126 millimeters and standard deviation=8 millimeters. If random sample of 37 bolts is selected, what is the probability that the sample mean would be less than 128 millimeters?
Air handling: The mean lifetime of a handheld leaf blower is reported to be 250 hours. A lawncare technician believes the actual lifetime to be less than 250 hours. A test is made of H:=250 versus H, : µ<250. The null hypothesis is rejected. State an appropriate conclusion. There (Choose one) venough evidence to conclude that the mean lifetime is (Choose one) ▼ 250 hours.

Rolling a die 50 times with a mean result = 3.08, median =3, mode=1, variance= 3.1536, and standard deviation=1.7758, Use the sample and test that the population mean for rolling a single die is 3.5.
Central limit theorem: Sample mean Seventy million pounds of trout are grown in the U.S. every year. Farm-raised trout contain an average (mean) of 32 grams of fat per pound, with a standard deviation of 8 grams of fat per pound. A random sample of 34 farm-raised trout is selected. The mean fat content for the sample is 31.5 grams per pound. Find the probability of observing a sample mean of 31.5 grams of fat per pound or less in a random sample of 34 farm-raised trout. Carry your intermediate computations to at least four decimal places. Round your answer to at least three decimal places. 0 ▬▬▬▬▬ 0/5 X 5 Español ? FRD
