In 2006, 75.9 percent of first-year college students responding to a national survey said that they used the Internet frequently for research or homework. A state university finds that 168 of an SRS of 200 of its first-year students said that they used the Internet frequently for research or homework. You wonder if the proportion of first-year students at this university who said that they used the Internet frequently for research or homework differs from the national value, 75.9 percent. Consider p as the proportion of first year college students at this university who use the Internet frequently for research or homework. The hypotheses that you will test are: H0: p = 0.759, Ha: p â 0.759

If the null hypothesis is true, the proportion who use the Internet frequently for research or homework from an SRS of 200 students would have (approximately) a Normal distribution with mean 0.759 and standard deviation . (Give your answer to four decimal places.)

(c) compare the results of parts (a) and (b). in general, how do you think the mode, median, and mean are affected when each data value in a set is multiplied by the same constant? multiplying each data value by the same constant c results in the mode, median, and mean increasing by a factor of c. multiplying each data value by the same constant c results in the mode, median, and mean remaining the same. multiplying each data value by the same constant c results in the mode, median, and mean decreasing by a factor of c. there is no distinct pattern when each data value is multiplied by the same constant. (d) suppose you have information about average heights of a random sample of airline passengers. the mode is 65 inches, the median is 72 inches, and the mean is 65 inches. to convert the data into centimeters, multiply each data value by 2.54. what are the values of the mode, median, and mean in centimeters? (enter your answers to two decimal places.) mode cm median cm mean cm in this problem, we explore the effect on the mean, median, and mode of multiplying each data value by the same number. consider the following data set 7, 7, 8, 11, 15. (a) compute the mode, median, and mean. (enter your answers to one (1) decimal places.) mean value = median = mode = (b) multiply 3 to each of the data values. compute the mode, median, and mean. (enter your answers to one (1) decimal places.) mean value = median = mode = --

Solve for the equation. 4x - 13 = 2x + 9
