The number of chocolate chips in an 18-ounce bag of chocolate chip cookies is approximately normally distributed with a mean of chips and standard deviation chips. Required:
a. What is the probability that a randomly selected bag contains between and chocolate chips, inclusive?
b. What is the probability that a randomly selected bag contains fewer than chocolate chips?
c. What proportion of bags contains more than chocolate chips?
d. What is the percentile rank of a bag that contains chocolate chips?

Explained below.

Step-by-step explanation:

The number of chocolate chips in an 18-ounce bag of chocolate chip cookies is approximately normally distributed with a mean of 1262 chips and standard deviation 118 chips.

(a)

Compute the probability that a randomly selected bag contains between 1000 and 1400 chocolate chips as follows:

Thus, the probability that a randomly selected bag contains between 1000 and 1400 chocolate chips is 0.8658.

(b)

Compute the probability that a randomly selected bag contains fewer than 1000 chocolate chip as follows:

Thus, the probability that a randomly selected bag contains fewer than 1000 chocolate chip is 0.0132.

(c)

Compute the proportion of bags that contains more than 1200 chocolate chips as follows:

Thus, the proportion of bags that contains more than 1200 chocolate chips is 0.2981.

(d)

Compute the percentile rank of a bag that contains 1125 chocolate chips as follows:

Thus, the percentile rank of a bag that contains 1125 chocolate chips is 12.3rd.

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
