We are supposed to find the probability that the high temperature on October 31 in a randomly chosen year will be between 46 degrees and 58 degrees
Formula :
at x = 46
Refer the z table for p value
p value = 0.3085
at x = 58
Refer the z table for p value
p value = 0.8413
Hence the probability that the high temperature on October 31 in a randomly chosen year will be between 46 degrees and 58 degrees is 0.5328
