- You are flipping two coins toghether for 'n' times. Suppose, the mean/expected number of double heads (H,H) you get is 16. Find the value of n.the time it takes to drive from Orangeville to the Vaughan Mills Mall is normally distributed with a mean of 52 minutes and standard deviation of 5 minutes. What intervals could you estimate without using the Z-score table and that do not include the mean as a max or min? For example, is an interval we know that includes the mean as the maximum of the interval. Another example is as an example of a probability interval that includes the mean as the minimum and 57 as the maximum. Include at least 7 intervals, their probabilities and a sketch in your answer.A recent survey of 1040 U.S. adults selected at random showed that 634 consider the occupation of firefighter to have very great prestige. Estimate the probability (to the nearest hundredth) that a U.S. adult selected at random thinks the occupation of firefighter has very great prestige.Step 1Recall that the probability of an event based on relative frequency uses the formulaprobability of event = relative frequency = fn,where f is the frequency of the event occurrence in a sample of n observations. A total of 1040 people were surveyed and 634 considered the occupation of firefighter to have very great prestige. Therefore, the sample size is n = . The event of interest is that a U.S. adult selected at random thinks the occupation of firefighter has very great prestige. Therefore, the frequency f is equal to the number of adults who the occupation of firefighter has very great prestige, so f = (0.6096 answer is incorrect.) .

She randomly selected six students and recorded their blood type. Suppose the probability of a student having blood type O is 0.45 and X be the number of students with blood type O. Which of the following is(are) TRUE about the experiment? A. It is a Bernoulli experiment with probability of success equal to 0.45B. The success in this experiment is observing six students with blood type O.C. X-Bin(6.0.45)D. A single trial of the experiment corresponds to six students.
