A company’s cereal boxes advertise that each box contains 9.65 ounces of cereal. In fact, the amount of cereal in a randomly selected box follows a Normal distribution with mean μ = 9.70 ounces and standard deviation σ = 0.03 ounce. Now take an SRS of 5 boxes. What is the probability that the mean amount of cereal in these boxes is less than 9.65 ounces?
a. 0.4525
b. 0.9522
c. 0.9999
d. 0.0478
e. 0.0001

0.0001

Step-by-step explanation:

Given

Mean μ=9.70

Sample size=n=5

standard deviation=σ = 0.03

Since its a normal distribution,so

σx=σ/

σx=0.03/

σx=0.0134

Now in order to use the table we have to to figure out z value.

z=(x-μ)/σ

z=(9.65-9.70)/0.0134

z=-3.73

From the probability index tables

So P(z≤-3.73)=0.0001

how am i supposed to answer

step-by-step explanation:

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
