The nicotine content in cigarettes of a certain brand is normally distributed with mean (in milligrams) u. The brand advertises that the mean nicotine content of their cigarettes is 1.5, but measurements on a random sample of 100 cigarettes of this brand gave a mean of = 1.53 and standard 1. deviation s = 0.1. Is there sufficient evidence in the sample to suggest that the mean nicotine content is actually higher than advertised? Use a = 0.01. (a) Set the appropriate hypotheses for the question. (b) Find the value of the standardized test statistic. (c) Find the rejection region. (d) What is your decision? (e) Find the p-value of this test.
The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 247.8 and a standard deviation of 63.6. (All units are 1000 cells/uL.) Using the empirical rule, find each approximate percentage below. a. What is the approximate percentage of women with platelet counts within 2 standard deviations of the mean, or between 120.6 and 375.0? b. What is the approximate percentage of women with platelet counts between 184.2 and 311.4? a. Approximately % of women in this group have platelet counts within 2 standard deviations of the mean, or between 120.6 and 375.0. (Type an integer or a decimal. Do not round.)

Determine the sample size required to estimate the mean score on a standardized test within 4 points of the true mean with 95 % confidence. Assume that s=15 based on earlier studies.
The pulse rates of 215 randomly selected adult males vary from a low of 33bpm to a high of 121 bpm. Find the minimum sample size required to estimate the mean pulse rate of adult males. Assume that we want 99% confidence that the sample mean is within 5 bpm of the population mean.
A researcher collected sample data for 15 women ages 18 to 24. The sample had a mean serum cholesterol level (measured in mg/100 mL) of 191, with a standard deviation of 5.6. Assuming that serum cholesterol levels for women ages 18 to 24 are normally distributed, find a 90% confidence interval for the mean serum cholesterol level of all women in this age group. Then find the lower limit and upper limit of the 90% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas.) Lower limit: I Upper limit:
The mean diastolic blood pressure for a random sample of 70 people was 96 millimeters of mercury. If the standard deviation of individual blood pressure readings is known to be 11 millimeters of mercury, find a 90% confidence interval for the true meandiastolic blood pressure of all people. Then give its lower limit and upper limit.
A researcher collected sample data for 16 women ages 18 to 24. The sample had a mean serum cholesterol level (measured in mg/100 mL) of 192.4, with a standard deviation of 9.6 Assuming that serum cholesterol levels for women ages 18 to 24 are normally distributed, find a 90% confidence interval for the mean serum cholesterol level of all women in this age group. Then find the lower limit and upper limit of the 90% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place.

Suppose a researcher wants to test if the average diastolic blood pressure in Irish-Americans is different than the average diastolic blood pressure in the general population. Note that the average diastolic blood pressure in the general population is 70 mmHG. The researcher recruits 30 Irish-Americans into this particular study and then measures each of their diastolic blood pressures (mmHG). The population of this sample has a standard deviation equal to 3.0, and the sample mean is 73. What is the test-statistic in this sample? Group of answer choices 5.477 1.000 30.000 5.385
A researcher collected sample data for 14 women ages 18 to 24. The sample had a mean serum cholesterol level (measured in mg/100 mt) of 193, with a standard deviation of 7.5. Assuming that serum cholesterol levels for women ages 18 to 24 are normally distributed, find a 90% confidence interval for the man serum cholesterol level of all women in this age group. Then find the lower limit and upper limit of the 90% confidence interval. Carry your intermediate computations to at least three decamal places. Round your answers to one deomal place.
A sample is selected from a population withu = 50. After a treatment is administered to the 16 individuals in the sample, the mean is found to be M = 55 and the standard deviation is s = 8, What is the test statistic for the sample mean?
