Nineteen individuals are scheduled to take a driving test at a particular DMV office on a certain day, eight of whom will be taking the test for the first time. Suppose that six of these individuals are randomly assigned to a particular examiner, and let X be the number among the six who are taking the test for the first time.
Compute P(X = 2), P(X ≤ 2), and P(X ≥ 2). (Round your answers to four decimal places.)
P(x=2) does not equal .3831
P(x <= 2) does not equal .2406
P(x >= 2) does not equal .7617

Can moving their hands help children learn math? This question was investigated in a study. Eighty-five children in the third and fourth grades who did not answer any questions correctly on a test with six problems of the form 3 + 2 + 8 = ___ + 8 were participants in an experiment. The children were randomly assigned to either a no-gesture group or a gesture group. All the children were given a lesson on how to solve problems of...

1. A hypothetical investigation on rider satisfaction with a particular public transit system serving commuting residents of British California (BC) and Prince Edward’s County (PEC) offers some interesting findings. The proportion of commuters from BC that indicated low satisfaction with the transit system’s service in the 2018 calendar year was 65 percent, and the proportion from PEC was 70 percent. These point estimates were based on samples of 5,380 BC commuters and 6,810 PEC commuters, whose system-using commuters number in...

2. It is estimated that 70% of all visitors to a given website are college students. The remaining 30% are either college graduates or have not attended college. Suppose the website had twelve visitors in the last two hours. (a) Let X be the number of visitors (among the twelve) who are college students. What assumptions need to be satisfied in order for X to obey a binomial distri bution? (b) Modeling X as a binomially distributed random variable, what...

For questions 13-16: Light exposure in mice Studies show that night-time light exposure is hamful to human health. A recent 6-week study randomly assigned lab mice to one of three conditions: LD (Group 1) had a standard light/dark cycle cach 24-hour period; (Group 2) LL had bright light all the time, and (Group 3) DM had dim light when there nomally would have been darkness. The rescarchers hoped to investigate...
