Random and independent samples of 65 recent prime time airings from each of two major networks have been considered. The first network aired a mean of 108.8 commercials during prime time, with a standard deviation of 5.2 commercials. The second network aired a mean of 111.2 commercials, with a standard deviation of 5.1 commercials. As the sample sizes are quite large, the population standard deviations can be estimated using the sample standard deviations. Construct a 99% confidence interval for μ1 - μ2, the difference between the mean number of commercials μ1 aired during prime time by the first network and the mean number of commercials μ2 aired during prime time by the second network. Then complete the table below
Carry your intermediate computations to at least three decimal places. Round your answers to at least two decimal places. (If necessary, consult a list of formulas.)
What is the lower limit of the 99% confidence interval?
What is the upper limit of the 99% confidence interval?
A simple random sample of front-seat occupants involved in car crashes in obtained. Among 2823 occupants not wearing seat belts
Construct frequency distribution tables for both the exports and imports data. Plot the frequency distributions on to one graph. Comment on your graphs.
(a) What is the probability of drawing a red chip from the bag? (b) Given that the chip that is drawn from the bag at the end is red, what is the conditional probability that the chip drawn from the box was white?
We want 95% confidence that the sample mean is within $5 of the population mean, and the population standard deviation is known to be $63.
a report states that 57 of home owners had a vegetable garden. how large a sample is needed to estimate the true
Your first IBM SPPS assignment includes two sections in which you will: Create two histograms and provide interpretations
Find the margin of error and construct a 90?% confidence interval for the population mean µ. Interpret the results.
Suppose a cylindrical glass with a diameter of 8 cm and a height of 10 cm is fully filled with a 400-Cal milkshake.
While dealing with 16 students, suppose that the alternative hypothesis has been one-sided and that it was set as Ha :
the height of a building is measured 32 times. the average of the measurements is 206 feet with standard deviation1.8
in a 10k run 27.4 of the runners finished the race in 49 minutes 42 seconds or faster. suppose that this result holds
What are the null and alternative hypotheses?- Check the assumptions necessary for inference.- Test the null hypothesis.
