4. The number of inaccurate gauges in a group of four is a binomial random variable s. a) What is the sample space of x (i.e., what values can s take on)? b) If on average 1 of 4 gauges tends to fail, obtain the probabilities for having one and two inaccurate gauges, respectively. c) Obtain the probability for having two or less (p 21 inaccurate gauges. d) Graph the probability distribution of x. Is the distribution symmetrical or skewed? e) What is the average and standard deviation of x?
Please read through the case scenario shown below to gain an understanding of the background information and the research study
Use the Limit theorem to find the mean and standard error
Calculate correlations among the portfolio, SH, and RWM and do you believe the relationships identified are stable and can thus be used going forward?

Find the 96th percentile of the distribution of reaction time (at least approximately). That is, find the value such that about 96% of the distribution is below this point - Find the probability the reaction time is 500 or less.
A typical adult has an average IQ score of 105 with a standard deviation of 20. If 20 randomly selected adults are given an IQ test, what is the probability that the sample mean scores will be between 85 and 125 points?
part-1- first reset the lower limit to zero and the upper limit to 1000 and then click update.- now put 6 points
