You want to estimate the percentage of adults who believe that passwords should be replaced with biometric security (such as fingerprints). How many randomly selected adults must you survey? Assume that you want to be 90% confident that the sample percentage is within 4.1 percentage points of the true population percentage. Complete parts (a) through (c) below. a. Assume that nothing is known about the percentage of adults who believe that passwords should be replaced with biometric security. The sample size needed is (Round up to the nearest whole number as needed.) b. Assume that a prior survey suggests that about 46% of adults believe that biometric security should replace passwords. The sample size needed is (Round up to the nearest whole number as needed.) c. Does the additional survey information from part (b) have much of an effect on the sample size that is required? The additional survey information from part (b) causes the required sample size to change by V 10%. Based on…
Two sections of statistics are offered, the first at 8 a.m. and the second at 10 a.m. The 8 a.m. section has 25 women, and the 10 a.m. section has 15 women. A student claims this is evidence that women prefer earlier statistics classes than men do. What information is missing that might contradict this claim? Question content area bottom Part 1 Choose the best answer below. A. The professor may be female in one class and male in the other, which could affect the female students' class preference. B. The percentage of female students in the two classes is unknown. There may be more females in the 8 a.m. because there are more students in the 8 a.m. class than the 10 a.m. class. This claim could be true only if the classes were the same size. C. The age and class standing of the students is unknown. Older female students may prefer later classes, so it may be only younger female students who prefer earlier classes. D. No information is…
Please give a detailed explanation, not just the response. If possible, a way to work out the problem in Excel is helpful! Thanks in advance!
