A researcher believes at 49% of people who grew up as the only child have an IQ score over 100. However, unknown to the researcher this figure is actually 50% which is the same as the general population. To attempt to find evidence for the claim, the researcher is going to take a random sample of 400 people who grew up as an only child. Let X be the proportion of people in the sample with an IQ score above 100. (a) find the mean of C (b) find the standard deviation of X (c) compute the approximation for P(x >0.49) , which is the probability that there will be 49% or more with the IQ scores over 100 in the sample. Round your answer to four decimal places. * greater than sign, is supposed to be greater than or equal to sign*
You run a candle manufacturing factory and over the past year the average output of the factory is 480 candles per day and the standard deviation is 10 candles per day. You plan to select 39 upcoming days at random and measure the outputs on those days. Then you will calculate the mean output in the sample of 39 days. What is the probability that the sample mean output will be within 3 candles of the population mean? z= ((x ̅- μ))/(s/√n) I got the probability is equal to 0.971. Is that correct?

Distributions A and B have the same mean and range. The standard deviations of distribution A and distribution B are 15 and 5, respectively. We may conclude that: the scores in distribution B are grouped closer to the mean than the scores in distribution A. the scores in distribution A are grouped closer to the mean than the scores in distribution B. there are three times as many scores from −1 standard deviation to +1 standard deviation in distribution A. there is one-third as many scores from −1 standard deviation to +1 standard deviation in distribution A. We cannot conclude anything unless we know the value of the mean.
