Question:
In Canada, households with internet spent an average of $410 annually for access. This distribution is non-normal: while roughly 59% of the households have high-speed access, many of the remaining households have limited dial-up access and pay much less. Assume the standard deviation is $138. If you ask an SRS of 600 households with internet access how much they pay, what is the probability that the average amount will exceed $420?
