Suppose the time it takes my daugther, Lizzie, to eat an apple is uniformly distributed between 6 and 10 minutes. Let X = the time, in minutes, it takes Lizzie to eat an apple. What is the probability that it takes Lizzie more than 11 minutes to finish the next apple? What is the probability that it takes Lizzie at least 7.2 minutes to finish the next apple? What is the probability that it takes Lizzie fewer than 6.3 minutes or more than 8 minutes to finish the next apple?
The table shows relative frequencies for red-green color blindness, where M represents "person is male" and C represents "person is color-blind". This study only used binary gender options. Use this table to find the probability P(M). P(M)= M M' Totals C 0.037 0.008 0.045 C' 0.436 0.519 0.955 Totals 0.473 0.527 1.000
When the health department tested private wells in a county for two impurities commonly found in drinking water, it found that 10% of the wells had neither impurity, 90% had impurity A, and 20% had impurity B. (Obviously, some had both impurities.) If a well is randomly chosen from those in the county, find the probability distribution for Y, the number of impurities found in the well. P(no impurities)= P(exactly one impurity)= P(both impurities)=
The United States Centers for Disease Control and Prevention (CDC) found that 17.9% of women ages 12–59 test seropositive for HPV‑16. Suppose that Tara, an infectious disease specialist, assays blood serum from a random sample of ?=1000 women in the United States aged 12–59. Apply the central limit theorem for the distribution of a sample proportion to find the probability that the proportion, ?̂, of women in Tara's sample who test positive for HPV‑16 is greater than 0.206. Express the result as a decimal precise to three places. Apply the central limit theorem for the distribution of a sample proportion to find the probability that the proportion of women in Tara's sample who test positive for HPV‑16 is less than 0.169. Express the result as a decimal precise to three places.

Suppose that 70% of Americans support the death penalty for persons convicted of murder. Let p> (p hat) be the sample proportion of proportion of people who support the death penalty in an SRS of Americans. Suppose we set our sample size to be n=84. What is the probability of choosing an SRS in which between 65% and 73% of the people in the people in the sample support the death penalty? That is, find P(0.65<p(phat)<0.73). Show your work and box your answer.

A car dealer is trying to sell five used cars. She attempts to sell a car to each customer that walks in. Suppose that only 7% of all the potential customers are willing and able to purchase a car, and assume that each customer acts independently of one another. Let X denote the number of customers that walk in before all five cars are sold. What is the distribution of X? What is the probability that the last car is sold to the 100th customer?
