A sociologist sampled 1800 people who work in computer-related jobs and found that 30% of them havechanged jobs in the last 6 months. We are interested in the proportion who have changed jobs.a) What parameter are we estimating? pb) What is the point estimate of that parameter? pc) What is a success for this problem? changed jobsd) How many successes were there?e) Find the margin of error for a 90% confidence interval, rounded to the 5th. Use your T-table for this.f) Round to the fourth.We are 90% confident that the true proportion of those who work in computer related jobs and havechanged jobs in the last 6 months is betweenand
