A researcher creates two random samples, each with a sample size of 8. He does not find a statistically significant difference between the two groups.
Which of the following statements is correct? Select all that apply.
A. Since random samples were used, the conclusion is likely to be
true.
B. Increasing or decreasing sample size does not impact the
outcome of a statistical analysis.
c. Since the sample size of each group is greater than 5, the
conclusion is likely to be true.
D. Since the sample size is so small, the conclusion is likely to be
untrue

An engineer is going to redesign an ejection seat for an airplane. the seat was designed for pilots weighing between 120 lb and 161 lb. the new population of pilots has normally distributed weights with a mean of 125 lb and a standard deviation of 28.1 lb. a)if a pilot is randomly selected, find the probability that his weight is between 120 lb and 161 lb.the probability is approximately? b. if 36 different pilots are randomly selected, find the probability that their mean weight is between 120 lb and 161 lb. the probability is approximately? c. when redesigning the ejection seat, which probability is more relevant? . part (b) because the seat performance for a single pilot is more important. b. part (b) because the seat performance for a sample of pilots is more important. c. part (a) because the seat performance for a sample of pilots is more important. d. part (a) because the seat performance for a single pilot is more important.
