Given a mean score of 1150, standard deviation of 90, and 500 participants, solve the following problem. Using this data and the

expeople1 [14]

Answer:

1. 1056.67

2. 29th percentile.

3. 79

4. 77

Step-by-step explanation:

Normal Probability Distribution

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean score of 1150, standard deviation of 90

This means that $\mu = 1150, \sigma = 90$

1. What is the score for someone in the 15th percentile?

This is X when Z has a p-value of 0.15, so X when Z = -1.037.

$Z = \frac{X - \mu}{\sigma}$

$-1.037 = \frac{X - 1150}{90}$

$X - 1150 = -1.037*90$

$X = 1056.67$

2. What is the percentile rank of someone with a score of 1100?

This is the p-value of Z when X = 1100. So

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{1100 - 1150}{90}$

$Z = -0.555$

$Z = -0.555$ has a p-value of 0.29, so 29th percentile.

3. How many students have scores of 1060 or greater?

The proportion is 1 subtracted by the p-value of Z when X = 1060. So

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{1060 - 1150}{90}$

$Z = -1$

$Z = -1$ has a p-value of 0.1587.

Out of 500:

0.1587*500 = 79

79 is the answer.

4. How many students scored between 1200 and 1250?

The proportion is the p-value of Z when X = 1250 subtracted by the p-value of Z when X = 1200. So

X = 1250

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{1250 - 1150}{90}$

$Z = 1.1$

$Z = 1.1$ has a p-value of 0.8643.

X = 1200

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{1200 - 1150}{90}$

$Z = 0.555$

$Z = 0.555$ has a p-value of 0.7106

0.8643 - 0.7106 = 0.1537

Out of 500:

0.1537*500 = 77

77 is the answer.

Ross had some stickers. He gave 297 of them to his sister.

Luba_88 [7]

Answer:

Ross has 450 stickers.

Step-by-step explanation:

Ross gave stickers to his sister = 297

If 66% of stickers Ross gave to his sister, how many stickers does Ross have?

Let Ross have stickers = x

So, we can write:

$66\% of x = 297$

Now solving this equation and finding value of x

$66\% of x = 297\\\frac{66}{100}\times x = 297\\x=297 \times \frac{100}{66}\\x=450$

We get x = 450. We know x= Number of stickers Ross has

So, Ross has 450 stickers.

Answer:

24

Step-by-step explanation:

36= 3 equal parts

so: 36/3 =12

One part=12

so 2 parts is 12*2
