It is reportedt that the average or mean number of Facebook friends is 155. Suppose that when 55 randomly chosen Facebook users are polled regarding the number of their friends, the averagenumber of their friends was reported to be x= 149 with a standard deviation of s= 29.2. The value z corresponding to the observed sample mean and standard deviation is -1.52.In USE SALTWhat is the probability of observing a value of z greater than 1.52 or less than -1.52? (Round your answer to four decimal places.)

Solution-: Let, Z-be the standard normal random variable We obtained P(Z>1.52) or P(Z<-1.52)=?…

Answered: It is reportedt that the average or…
