The director of a hospital wishes to estimate the mean number of people who are admitted to the emergency room during a 24-hour period.
The director randomly selects 36 different 24-hour periods and determines the
number of admissions for each.
For this sample, x = 15.8 and s2 = 9
Estimate the mean number of admissions per 24-hour period with a 98% confidence
interval.
O 15.8 + 1.165
O 15.8 + 3.495
O 15.8 + 1.94
O 15.8 + .490

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
