The amount of marinara sauce on the spaghetti at pasta infusion follows a normal distribution, with a mean of 3.25 ounces and a standard deviation of 0.2 ounce. a random sample of 10 plates of spaghetti is selected every day and the sauce is measured. what is the probability that the mean weight will exceed 3.3 ounces?

a. 0.2146
b. 0.7854
c. 0.4013
d. 0.5987
e. 0.7905

A. 0.2146

Step-by-step explanation:

The mean and standard deviation of the sample is:

μ = 3.25

σ = 0.2 / √10 = 0.063

The z-score is:

z = (x − μ) / σ

z = (3.3 − 3.25) / 0.063

z = 0.79

The probability is therefore:

P(z > 0.79) = 0.2146

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.
