Question

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 $2.712 per gallon. A random sample of 36 gas stations is drawn from this population. What is the probability that the mean price for the sample was between $2.692 and $2 732 that week? Assume : SO 046 board pages ent course ! The probability that the sample mean was between $2692 and S2722s 17FA ACC-121-01 (Round to four decimal places as needed.) articipants Badges General elirkth rnn to view nana 1 of tha ct andard nnr mal tahla

Explanation / Answer

n = 36

z1 = (2.692 - 2.712)/0.046/36 = - 2.61

z2 = (2.732 - 2.712)/0.046/36 = + 2.61

So, P(- 2.61 < z < 2.61) = 0.9909
