(1pt)What is the standard error? Show work. (1pt)What is the margin of error for a 90% confidence interval? Show work. (2pts)Construct a 90% confidence interval for the population mean. Show work(2pts)Based on your interval, are the two studies consistent? Give reason(s) (1pt)How will decreasing the confidence level affect the interval? (1pt)If we sampled more households, how would this affect the margin of error? (1pt)How would you explain the term confidence interval to someone with no statistical knowledge? (1pt)
