According to a poll of adults, about 44% work during their summer vacation. Assume that the true proportion of all adults that work during summer vacation is p = 0.44. Now consider a random sample of 400 adults.a. What is the probability that between 39% and 49% of the sampled adults work during summer vacation?The probability is. (Round to three decimal places as needed.)ISb. What is the probability that over 60% of the sampled adults work during summer vacation?The probability is. (Round to three decimal places as needed.)IS

We have given that Sample size n= 400 Success of probability = 0.44

The Census Bureau gives this distribution for the number of people in American households in 2016. Family size 1 2 4 6. 7 Proportion 0.28 0.35 0.15 0.13 0.06 0.02 0.01 Note: In this table, 7 actually represents households of size 7 or greater. But for purposes of this exercise, assume that it means only households of size exactly 7. Suppose you take a random sample of 4000 American households. About how many of these households will be of size 2? Sizes 3 to 7? The number of households of size 2 is about The number of households of size 3 to 7 is about

A researcher selects a sample of 6 men and 11 women. She asks participants to rate the likelihood they would do female-stereotyped jobs (such as nursing or school teaching) on a scale from 1 = not likely at all to 5 = very likely. Men indicated that they would be less likely to do these jobs (M = 2.1) compared with women (M = 4.3). What is the weighted mean for the combined sample of 17 total participants? O O 2.1 4.3 3.2 3.5
