A sample of 140 Vopstra customers have had their annual phone charge recorded for the previous calendar year. The data were used

taurus [48]

Answer:

Correct option: (a)

Step-by-step explanation:

A confidence interval is an interval estimate of the parameter value.

A (1 - α)% confidence interval implies that the confidence interval has a (1 - α)% probability of consisting the true parameter value.

If 100 such confidence intervals are made then (1 - α) of these intervals would consist the true parameter value.

The 92% confidence interval for the mean annual phone charge of all Vopstra customers is:

$\$470\pm \$65=(\$405, \$535)$

This confidence interval implies that true mean annual phone charge of all Vopstra customers is contained in the interval ($405, $535) with 0.92 probability.

Thus, the correct option is (a).

What you did is set πr² equal to A then divide the π by both sides so it will cancel on the right side and keep A over π then square root r to cancel the exponent of 2
