okay first lets look at the question once again $24? 1. Taxi Fares are normally distributed with mean fare $22.27 and a standard deviation of $2.20.

A) What is the probability of a single Taxi fare being over $24? 0.2158

What is the probability that the average of a random sample of 10 taxi fares being over 'Sd=22 0068

B) Which should have a greater probability of being between $12 and $24 - the mean of 10 randomly selected taxi fares or the amount of a single randomly selected taxi fare? Why?​

So for A. its i dont know

and for B. its i dont know either
