n = 72 , p = 0.27
mean = np = 72*0.27 = 19.44
sd = sqrt(npq) = sqrt(72*0.27 * 0.73)= 3.767
option 5) is correct

Question 6 (2 points) A dating app allows users to swipe right to 'like' or left to pass when they view a person's dating profile. You want to estimate the overall "success rate for men from women viewing their dating profile. You randomly select 400 swipes where women viewed men's profiles and 68 of the 400 swipes were swiped right. The margin of error on your estimate is 3.7% at the 95% confidence level. What is the best-case estimate of...

6. A new app start-up claims that "no more than than 6% of the product reviews they receive are negative" but we suspect it is more. When examining a random sample of 2000 reviews, we find that 140 are negative Let p be the probability that a review is negative and let X, (i 1,.. ,2000) be the random variable that represents the ith review being negative (assume they are independent and identically distributed). (a) Identify an appropriate probability model...
