Suppose an advocacy organization surveys 847 Canadians and 444 of them reported being born in anothercountry. Similarly, 16 out of 119 U.S. citizens reported being foreign-born. Find the standard error of the difference inthe two proportions.Let p, be the sample proportion of citizens from Canada who reported being born in another country and p2 be thesample proportion of citizens from the U.S. who reported being foreign-born.The standard error of the difference in the two proportions SE (P₁-P₂) =(Round to four decimal places as needed.)

Given that: Sample 1(Canadians): x1=444n1=847 Sample 2(U.S. Citizens): x2=16n2=119

To get an unbiased sample variance, we divide by instead of which would give us a estimate of the variance.
An athletic shoemaker wants to test if their new running shoe specially made for sprinting is better than the competition. To do this, they recruit 35 NCAA sprinters and time their 100-meter dash wearing the company's shoe and then time their 100-meter dash again wearing the competitor’s shoe. The difference of these times is then calculated asTimecompany.shoe−Timecompetitor.shoe. The sample mean difference in times is 0.53 seconds and the sample standard deviation is 1.1. Conduct a hypothesis test at theα=0.1 level. (a) Set up the null and alternative hypothesis (using mathematical notation/numbers AND interpret them in the context of the problem) (b) Calculate the test statistic (c) Calculate the critical value. (d) Draw a picture of the distribution of the test statistic underH0. Label and provide values for the critical value and the test statistic, and shade the critical region.

Newborn babies are more likely to be boys than girls. A random sample found 13,173boys were born among 25,468 new born children. The sample proportion of boys was0.5172. Is this sample evidence that the birth of boys is more common than the birth ofgirls in the entire population?
Suppose a community college has 10,000 students (the population). We are interested in the average amount of money a part-time student spends on books in the fall term. Asking all 10,000 students is almost an impossible task. A sample is taken using a list of students who take photography classes, and each of these students is surveyed. Do you think that this sample is representative of the entire 10,000 student population? Why or why not?
