Okay, so the total cookies is given by 22 cookies (the ones given to the students) plus 27 cookies (the ones left over) Therefore there were 49 cookies in total. Subtract the 24 cookies from the first batch, and you have 25 cookies remaining, which is the total from the second batch. 

25 cookies.

24 cookies in the first batch
Unknown in the second, let's call it "x".
The total amount of cookies is the amount of cookies eaten by students (22) as well as the amount left (27).
We can set these equivalent to one another:
24+x=22+27
24+x=49
subtract 24 from both sides
24+x=49
-24     -24
x=25
So, there were 25 cookies in the second batch.

Which of the following statements about the percentiles for the standard normal distribution are correct? A. The 90th percentile
shutvik [7]

Answer:

Correct option: (C) The 75th percentile is approximately 0.67

Step-by-step explanation:

The <em>p</em>th percentile is a data value such that at least <em>p</em>% of the data set is less than or equal to this data value and at least (100 - <em>p</em>)% of the data set are more than or equal to this data value.

If <em>x</em> is the <em>p</em>th percentile of a data set then,

P (X < x) = p/100

If X\sim N(\mu, \sigma^{2}) then  Z=\frac{X-\mu}{\sigma}, is a standard normal variate with mean, E (Z) = 0 and Var (Z) = 1. That is, Z \sim N (0, 1).

  • The 90th percentile of a standard normal distribution is:

        P (Z < z) = 0.90, then <em>z</em> = 1.28

  • The 10th percentile of a standard normal distribution is:

        P (Z < z) = 0.10, then <em>z</em> = -1.28

  • The 75th percentile of a standard normal distribution is:

        P (Z < z) = 0.75, then <em>z</em> = 0.67

  • The 15th percentile of a standard normal distribution is:

        P (Z < z) = 0.15, then <em>z</em> = -1.04

Thus, the correct statement is (C).
