The numbers of cookies in a shipment of bags are normally distributed, with a mean of 64 and a standard deviation of 4. what percent of bags of cookies will contain between 60 and 68 cookies? a. 50% b. 13.5% c. 68% d. 34% show your work .

C. 68%  

Step-by-step explanation:

We have been given that the numbers of cookies in a shipment of bags are normally distributed, with a mean of 64 and a standard deviation of 4.

Let us find z-score for our given raw scores 60 and 68 using z-score formula.

, where,  

z= z-score.

x= Raw score.

= Mean.

= Standard deviation.

Therefore, 60 is 1 standard deviation below mean.

Now let us find z-score for 68.

Therefore, 68 is 1 standard deviation above mean.

We can see that 60 and 64 lies between z=-1 and z=1.

Since empirical rule states that 68% of data falls within the first standard deviation from the mean, therefore, 68% of cookie bags will contain between 60 and 68 cookies and option C is the correct choice.

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

answer: yes i agree that you should not put it on/p>

step-by-step explanation: the reason for this is that it wastes other peoples time and also make them fail as well and that is never good.
