# Q10 - investigate

A nutritionist who investigates fruits reported that the average weight of a raspberry is 4.4 g with a standard deviation of 1.28 g. What is the probability that a randomly selected raspberry would weigh less than 3.1 grams?

Let X represent the weight of a randomly selected raspberry. Assume the distribution of weights is approximately normal. Find P( X < 3.1).

p =  0.16

it says round your answer to 2 decimal places, but marks 0.16 wrong (solution says 0.1587 which would round to 0.16). In addition I think the solution is also wrong, (3.1-4.4)/1.2 = -1.015625 which would be more like -1.01 or -1.02 on a ztable, 0.1587 is the ztable value for -1.00 which seems wrong to me.
