Question
The number of adult Americans who support a bill proposing to extend daylight savings time is a discrete random variable. Assume that its probability will be approximated using the normal distribution. Describe the area under the normal curve that will be computed in order to determine the probability that more than
318
Americans support the bill.
Describe the area under the normal curve. Choose the correct answer below.
Right of
x=318
Right of
x=317.5
Right of
x=318.5
Left of
x=317.5
Between
x=317.5
and x
=318.5
Left of
x=318.5
Explanation / Answer
Right of x=318.5
The probability of the event is calculated after applying continuity correction. In this case, we need to calculate the probability of more than 318, which doesnt include 318. So, we need to consider the value above 318 and should be towards the right.
