Find the probability and interpret the results. If convenient, use technology to find the probability. During a certain week the mean price of gasoline was $2.7042.704 per gallon. A random sample of 3131 gas stations is drawn from this population. What is the probability that the mean price for the sample was between $2.6982.698 and $2.7172.717 that week? Assume sigmaσequals=$0.0440.044.

The probability that the mean price for the sample was between $2.6982.698 and $2.7172.717 that week is P=0.726.

Step-by-step explanation:

We have a population mean price of $2.704. The standard deviation is $0.044.

We draw a sample of size n=31 out of this population.

We have to calculate the probability that the mean price for this sample is between $2.698 and $2.717 that week.

To calculate this, first we calculate the z-scores for both values:

X1=2.698

X2=2.717

Then, we have:

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5

false
