Chapter 1.2, Problem 21E

In Exercises 9-34, because different rounding results in different estimates, there is not one single, correct answer to each exercise.

In Exercises 9-22, obtain an estimate for each computation by rounding the numbers so that the resulting arithmetic can easily be performed by hand or in your head. Then use a calculator to perform the computation. How reasonable is your estimate when compared to the actual answer?

"Save today by switching to SOAR!" is the slogan for SOAR, a cell phone service provider. Logan wants to estimate how much money customers who switch to SOAR save on their monthly bill. He surveys 75 people who have recently switched to SOAR and asks each one how much they are saving in their monthly bill as a result of the switch. He finds the average savings of the sample to be $19.03 and historical records indicate that o = $4.71 What is the standard error in estimating monthly phone bill savings? 0.895 0.544 4.710 0.236
