Answer:

d. There is a relationship between gender and intended major.

According to the above question, we can see that most women used in research want to continue the psychology course, while most men want to continue the history course. With this we can conclude that there is a greater relationship between the female gender and the psychology course (according to this research), as there is a greater relationship with the male gender and the history course. For this reason, we can state that the results of this research show that there is a relationship between gender and main intention.

nika2105 [10]

The complete question is:

Scores on the SAT test have a mean of 1518 and a standard deviation of 325. Scores on the ACT test have a mean of 21.1 and a standard deviation of 4.8. Which of the following choices is <u>NOT</u> true?

Options:

A) The ACT score of 17.0 is relatively better than the SAT score of 1490

B) An SAT score of 1490 has a z score of -0.09

C) The SAT score of 1490 is relatively better than ACT score of 17.0

D) An ACT score of 17.0 has a z score of -0.85

<h2>Answer:</h2><h2 />

<em><u>C) The ACT score of 17.0 is relatively better than the SAT score of 1490:</u></em><em> </em><u>NOT true</u>

<h2>Explanation:</h2><h2></h2>

To compare scores on different scales or from different groups you need to use a normalized standardized statistic, like the z-score.

$z-score=(score-\mu)/\sigma$

Where $\mu$ is the mean of the sample, and $\sigma$ is the standard deviation.

<u>1. Find the z-core for an ACT score of 17.0 </u>

$z-score=(score-\mu)/\sigma\\ \\ z-score=(17.0-21.1)/4.8\\ \\ z-score=-0.85$

That means that the ACT score of 17.0 is 0.85 standard deviations below the meqan.

<u>2. Find the z-score for an SAT score of 1490</u>

$z-score=(score-\mu)/\sigma\\ \\ z-score=(1490-1518)/325\\ \\ z-score=-0.086\approx -0.09$

That means that the SAT score of 1490 is 0.09 standard deviations from the mean.

<u>3. Conlusion:</u>

Since the z-score of the SAT score of 1490 is greater than the z-score of the ACT of 17.0, the SAT score of 1490 is relatively better than the aCT score of 17.0.

As for the answer choices:

<em>A) The ACT score of 17.0 is relatively better than the SAT score of 1490</em>: NOT true. ← correct answer

<em>B) An SAT score of 1490 has a z score of -0.09</em>: TRUE

<em>C) The SAT score of 1490 is relatively better than ACT score of 17.0</em>: TRUE

<em>D) An ACT score of 17.0 has a z score of -0.85</em>: TRUE.
