Suppose the lengths of the pregnancies of a certain animal are approximately normally distributed with mean u = 286 days and standard deviation o = 23 days. Complete parts (a) through (f) below. Interpret this probability. Select the correct choice below and fill in the answer box within your choice. (Round to the nearest integer as needed.) O A. If 100 pregnant individuals were selected independently from this population, we would expect pregnancies to last exactly 279 days. O B. If 100 pregnant individuals were selected independently from this population, we would expect pregnancies to last more than 279 days. O C. If 100 pregnant individuals were selected independently from this population, we would expect pregnancies to last less than 279 days.

You are a doctor ,a and on average you meet with 30 patients per day. Assuming the NHANES dataset is representative of your patient population, calculate the following.  1. The probability of a single individual having health insurance. = 0.8807812125569134 2. The probability that 3 people in a row will not have health insurance. 3. The probability that 1/3 of your 30 patients for the day do not have health insurance

In an election, suppose that 35% of voters support a school levy increase. If we poll 220 of these voters at random, the probability distribution for the proportion of the polled voters that support a school levy increase can be modeled by the normal distibution pictured below. Complete the boxes accurate to two decimal places .
