Adults from the general population have IQ scores that are normally distributed with a mean = 100 and a standard devation of = 15. If a single adult is randomly selected, what is the probability that the subject has an IQ score less that 70? Round to 4 decimal places? P(x < 70) = If a single adult is randomly selected, what is the probability that the subject has an IQ score between 85 and 115? Round to 4 decimal places. P(85 < x < 115) = If a single adult is randomly selected, what is the probability that the subject has an IQ score greater than 140? Round to 4 decimal places? P(x > 140) = Bb Welcome, luli A sample of n = 100 members of American Mathematical Society has a sample mean of 103. Assuming that the distribution of IQ score of AMS members is same as the general population, what is the probability of selecting a random sample of n = 100 adults with the sample mean that is greater than 103? Round to 4 decimal places. P(>103) = - What statement best describes the sample event in the previous question? The event is unlikley, because the probability is less than 0.05 The event is unlikley, because the probability is more than 0.05 The event is not unlikley, because the probability is less than 0.05 The event is not unlikley, because the probability is more than 0.05 A member of the AMS claims that the mean IQ score of MAS members is actually higher than the general population. Given the observation above, what statement best fits that claim? That claim is not supported because the event above is unlikely otherwise. That claim is supported because the event above is unlikely otherwise. That claim is not supported because the event above is not unlikely otherwise. That claim is supported because the event above is unlikely otherwise.
