The annual cost of diapers for families that have one or more children under the age of 4 is skewed to the right with a mean of $1,225 and a standard deviation of $633. If a random sample of 15 families that have one or more children under the age of 4 are selected, what is the probability that their mean annual diaper cost is more than $1,500? Is it appropriate to calculate this probability? If yes, use this standard Normal table to calculate the probability and select the correct probability. If no, then select "Not appropriate." ​

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
