Question

*please show work if possible* trying to chekc my own work!

According to a poll of adults about 41% work during their summer vacation. Suppose that this claim about the population proportion is true. Now if we take a sample of 79 adults, and find the sample proportion ["(p)) of adults who work during summer vacation What is the expected value of sample proporion(p)]? What is the standard deviation of sample propotion(p)]? The shape of the sampling distribution of sample proportion [^(p)] will be roughly like a O normal distribution Submit Answer Tries 0/5 Submit Answer Tries 0/5 uniform distribution Ostudent's t distribution binomial distribution Poisson distribution Submit Answer Tries 0/3 P(0.35 [M(p)] 0.50) Submit Answer Tries 0/5 Is the sample large enough to compute the above probability? Yes, because np 10 and n(1-p) 10 O Yes, because the number of successes and failures are both larger than 10 Yes, because n 2 30 O No, the sample size is not sufficiently large. We actually had to assume normally distributed population. Yes, because np 2 10 Submit Answer Tries 0/3 Find c such that P((p) 2 c) 0.6 Submit Answer Tries 0/5
