A nurse found that the lengths of babies in a hospital have a normal distribution with mean u and standard deviation o. He found that the length of 9.92% of the babies were less than 59.2 cm and the length of 9.92% of the babies were more than 73.6 cm. Find the values u and o. 250 babies are chosen at random. Find the expected number of babies which have a length of between 70 cm and 72.5 cm by using the answer (3 significant figures) in part (i).

A study of pregnant women found that the length of pregnancies is normally distributed with a mean of 269 days and a standard deviation of 14 days. A baby is said to be premature if the length of pregnancy is in the lowest 3% of pregnancy durations. Find the length of pregnancy in number of days that separates the premature babies from the mature babies.
A researcher studying stress is interested in the blood pressure measurements of chief executive officers (CEOS) of major corporations. He believes that the mean systolic blood pressure, u, of CEOS of major corporations is less than 134 mm Hg, which is the value reported in a possibly outdated journal article. He plans to perform a statistical test. He measures the systolic blood pressures of a random sample of CEOS of major corporations and finds the mean of the sample to be 122 mm Hg and the standard deviation of the sample to be 15 mm Hg. Based on this information, answer the questions below. What are the null hypothesis (H) and the alternative hypothesis (H,) that should be used for the test? H: u is ? H: u is ? In the context of this test, what is a Type II error? A Type II error is ? fact, u is ? v the hypothesis that u is ? when, in Suppose that the researcher decides not to reject the null hypothesis.

Dominic would want to estimate the mean of a population which is normally distributed. The standard deviation is 4. A random sample was drawn and the sample points are: 7, 8, 8, 9. Furthermore, the sample mean was used as an estimator. What are the given mean and standard deviation?
During a wisdom teeth removal procedure, 1, 2, 3, or 4 wisdom teeth are removed, depending on the patient's needs. Records indicate that nationwide, the mean number of wisdom teeth removed in a procedure is u= 3.50, with a standard deviation of o=1.27. Suppose that we will take a random sample of 6 wisdom teeth removal procedures and record the number of wisdom teeth removed in each procedure. Let ī represent the sample mean of the 6 procedures. Consider the sampling distribution of the sample mean x. Complete the following. Do not round any intermediate computations. Write your answers with two decimal places, rounding if needed. (a) Find (the mean of the sampling distribution of the sample mean). (the standard deviation of the sampling distribution of the sample mean). ?
An insurance company wants to know if the average speed at which men drive cars is greater than that of women drivers. The company took a random sample of 54 cars driven by men on a highway and found the mean speed to be 144 miles per hour with a standard deviation of 4.4 miles per hour. Another sample of 36 cars driven by women on the same highway gave a mean speed of 136 miles per hour with a standard deviation of 5 miles per hour. Assume that the speeds at which all men and all women drive cars on this highway are both normally distributed with an equal population standard deviation. 1.Construct a 98% confidence interval for the difference between the mean speeds of cars driven by all men and all women on this highway. please give correct answer and as soon as possible
