The difference (faculty-student) in the sample proportions of those who believe that five minutes is not enough time for students to change classes typically varies about 0.096 from the true difference in proportions. Option D is correct.
<h3>What is the standard deviation?</h3>
It is a measurement of statistical data dispersion. The degree to which the value varies is known as standard deviation.
The standard deviation of the sampling distribution is found as;
![\rm \sigma_F-\sigma_s= \sqrt{\frac{0.37 \times (1-0.37)}{28}+\frac{0.89 \times (1-0.89)}{100} } \\\\ \sigma_F-\sigma_s=0.096](https://tex.z-dn.net/?f=%5Crm%20%5Csigma_F-%5Csigma_s%3D%20%5Csqrt%7B%5Cfrac%7B0.37%20%5Ctimes%20%281-0.37%29%7D%7B28%7D%2B%5Cfrac%7B0.89%20%5Ctimes%20%281-0.89%29%7D%7B100%7D%20%20%7D%20%5C%5C%5C%5C%20%20%5Csigma_F-%5Csigma_s%3D0.096)
The difference in the sample proportions of those who think five minutes is not enough time for students to switch classrooms generally differs by roughly 0.096 from the actual difference in proportions.
Hence option D is correct.

Answer:
2
Step-by-step explanation:
Each image point is twice as far from the origin as its preimage point. Each image segment is twice as long as its preimage segment. (LM=2, L'M'=4, for example)
The scale factor is 2.
8/15 or somthing like that it you might be souposed to solve it diferent than i did
