Assume the random variable x is normally distributed with meanmu equals 50μ=50and standard deviationsigma equals 7σ=7.compute the probability. be sure to draw a normal curve with the area corresponding to the probability shaded. upper p left parenthesis 34 less than upper x less than 63 right parenthesisp(34

0.9575465

Step-by-step explanation:

Let the random variable X is normally distributed with mean and standard deviation .

Using the formula , , we have the z-value for x= 34

For x= 63

P-value : P(34<x<63)=P(-2.29<z<1.86)

Hence, the required probability = 0.9575465

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
