Internet Service Providers The amount that households pay service providers for access to the Internet varies quite a bit, but the mean monthly fee is $50 and the standard deviation is $20. The distribution is not Normal: many households pay a low rate as part of a bundle with phone or television service, but some pay much more for Internet only or for faster connections. A sample survey asks an SRS of 50 households with Internet access how much they pay. Let x be the mean amount paid. 1. Explain why you can't determine the probability that the amount a randomly selected household pays for access to the Internet exceeds $55. 2. What are the mean and standard deviation of the sampling distribution of x ? 3. What is the shape of the sampling distribution of x ? Justify your answer. 4. Find the probability that the average fee paid by the sample of households exceeds $55.
Assume you have taken 125 samples of size 81 each from a population. The population variance is 64. What is the standard deviation of each (and every) sample mean? 0.5 0.89 9 8
I. Normal Distribution A teacher gives the following assignment to 200 students: Check the local newspaper every morning for a week and count how many times the word "gun" is mentioned on the "local news" pages. At the end of the week, the students report their totals. The mean result is 85, with a standard deviation of 8. The distribution of scores is normal. a. How many students would be expected to count fewer than 70 cases? Show the solution and draw the normal curve b. How many students would be expected to count between 80 and 90 cases? Show the solution and draw the normal curve c. How many students would be expected to count higher than 60 cases? Show the solution and draw the normal curve
The amount of trash generated by US households (in lbs per day) is normally distributed. You take a sample of 10 people. The sample average is xbar=10.91 lbs, and the sample standard deviation is s=4.736. What is the 99% Conf. Int. for the mean? Group of answer choices a. 6.04 to 15.78 b. 8.33 to 13.49 c. 8.09 to 13.73 d. 7.74 to 14.08
A simple random sample of 100 observations was taken from a large population. The sample mean and the standard deviation were determined to be 81 and 9 respectively. The standard error of the mean (i.e. the standard error of the sampling distribution) is 8.10 0.90 O 0.81 O 0.27 Clear my choice
eighteen different video games showing alcohol use were observed. The duration times of alcohol use (in seconds) were recorded. When using this sample for a t test of the claim that the population mean is greater than 83 sec, what does df denote, and what is its value? What does df denote? A. The number of degrees of freedom B. The test statistic C. The sample standard deviation D. The sample size The value of df is
