Twenty-six percent of people in the United States with internet access go online to get the news. A random sample of five Americans with internet access is selected and asked if they get the news online. Let the random variable X- the number of people who go online to get the news. a. Construct a probability distribution table. b. Calculate the mean. c Calculate the variance to the nearest thousandth. d. Calculate the standard deviation to the nearest thousandth.

76% of U.S. adults think that political correctness is a problem in America today. You randomly select six U.S. adults and ask them whether they think that political correctness is a problem in America today. The random variable represents the number of U.S. adults who think that political correctness is a problem in America today. Answer the questions below. 1.mean of the binomial distribution 2.variance of the binomial distribution 3.standard deviation

Find the standard deviation. Group 1: 7,8,7,6,7,7,7

Eighty-three percent of adults in a certain country believe that life on other planets is plausible. You randomly select five adults and ask them whether they believe that life on other planets is plausible. The random variable represents the number of adults who believe that life on other planets is plausible. Find the​ mean, variance, and standard deviation of the binomial distribution for the random variable. Interpret the results   find the mean, variance, and standard deviation

O Macmillan Learning The domestic cat, Felis catus, is a domesticated furry creature often kept as a pet in many countries. Suppose a volunteer at a local animal shelter wanted to find out a little more about the cats in her care. The volunteer carefully measured the height for the 10 fully grown adult cats at her shelter. The height measurements were taken from the base of the foreleg to the shoulder. The table shows the results of the measurements. Calculate the mean, variance, and standard deviations for cat height for the sample of shelter cats. Report all your answers to two decimal points. mean: variance: standard deviation: in in² in Sample 1 2 3 4 5 6 7 8 9 10 Height (in) 10.5 13 7.7 7.5 9.55 10.5 10.85 12.3 8.15 7.85
