question 1. In the accompanying table, the random variable x represents the number of televisions in a household in a certain country. Determine whether or not the table is a probability distribution. If it is a probability distribution, find its mean and standard deviation. A. If the table is a probability distribution, what is its mean? Select the correct choice below and fill in any answer boxes within your choice b. If the table is a probability distribution, what is its standard deviation? Select the correct choice below and fill in any answer boxes within your choice. Question 2 Determine whether or not the procedure described below results in a binomial distribution. If it is not binomial, identify at least one requirement that is not satisfied. Five hundred different voters in a region with two major political parties, A and B, are randomly selected from the population of 5.2 million registered voters. Each is asked if he or she is a member of political party A, recording Yes or No. Choose the correct answer below. A. No, the probability of success is not the same in all trials. B. No, the trials are not independent and the sample is more than 5% of the population. C. Yes, the result is a binomial probability distribution. D. No, the number of trials is not fixed. E. No, there are more than two possible outcomes. Question 3. Assume the readings on thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. Find the probability that a randomly selected thermometer reads between −2.15 and −0.35 and draw a sketch of the region. Draw a sketch and probability is ? (Round to four decimal places as needed.) question 4 If np ≥5 and nq ≥5, estimate P(more than 8) with n=11 and p=0.7 by using the normal distribution as an approximation to the binomial distribution; if np<5 or nq <5, then state that the normal approximation is not suitable Select the correct choice below and, if necessary, fill in the answer box to complete your choice A. P(more than 8)= (Round to four decimal places as needed.) B. The normal distribution cannot be used.
