4. A sample of human brain volumes (cm) is given below. Use the given data values to identify the corresponding z scores that are used for a normal quantile plot, then identify the coordinates of each point in the normal quantile plot. Construct the normal quantile plot, then determine whether the data appear to be from a population with a normal distribution. 1022 1421 1082 1053 1072 1082 955 1063 List the z scores for the normal quantile plot. .0.0.0.0.0. 0.0 (Round to two decimal places as needed. Use ascending order.)5. Use a normal approximation to find the probability of the indicated number of voters. In this case, assume that 178 eligible voters aged 18-24 are randomly selected. Suppose a previous study showed that among eligible voters aged 18-24, 22% of them voted. Probability that fewer than 44 voted The probability that fewer than 44 of 178 eligible voters voted is (Round to four decimal places as needed.)6. When a scientist conducted a genetics experiments with peas, one sample of offspring consisted of 947 peas, with 743 of them having red flowers. If we assume, as the scientist did, that under these circumstances, there is a 3 /4 probability that a pea will have a red flower, we would expect that 710.25 (or about 710) of the peas would have red flowers, so the result of 743 peas with red flowers is more than expected. a. If the scientist's assumed probability is correct, find the probability of getting 743 or more peas with red flowers. b. Is 743 peas with red flowers significantly high? c. What do these results suggest about the scientist's assumption that 3/ 4 of peas will have red flowers? a. If the scientist's assumed probability is correct, the probability of getting 743 or more peas with red flowers is (Round to four decimal places as needed.)
