In a poll, 37% of the people polled answered yes to the question "Are you in favor of the death penalty for a person convicted of murder?" The margin of error in the poll was 5%, and the estimate was made with 94% confidence. At least how many people were surveyed?

The number of people surveyed was 330.

Step-by-step explanation:

The (1 - α)% confidence interval for the population proportion is:

The margin of error for this interval is:

The information provided is:

The critical value of z for 94% confidence level is, z = 1.88.

*Use a z-table.

Compute the value of n as follows:

Thus, the number of people surveyed was 330.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=
