dimaraw [331]

Answer:

Option C. The real effect is 0.1

Step-by-step explanation:

The complete question is  

You are interested in the psychological implications of high SES. You read a paper that claims that higher social class people behave more unethically. The paper reports a significant difference in the propensity of high and low SES people behaving unethically. The significance level of this study was 0.05, the ratio of true to false effects in this field is 0.35, but the author was anxious to issue a press release and prepare his TED talk, so power is low, at 0.1. The probability that this study reports a real effect is

A. 0.58

B. 0.95

C. 0.1

D. 0.35

E. 0.41

Solution

Ratio of true to false effects i.e T/F = 0.35  

The power of the study indicates the real effect of the study and hence despite the true/false ration being 0.35 and the significance level of study is 0.05, the real effect of the study would be 0.1

Hence option C is correct

If 75% of the students in a middle school ride the bus home, and that is 225 students, how many students are there in the middle
BartSMP [9]
Hello! I think that 300 students attend that middle school. Since 225 is 75% of the students all I did was make 75% a fraction, which is 3/4. Then, I figured out that 225/300 is equivalent to 3/4 or 75%.

A factor of 30 is chosen at random, what is the probability that the number has 2 digits?
mihalych1998 [28]

Answer:

3/8

Step-by-step explanation:

Let's first start by figuring out all the factors of 30.

They are as follows: 1, 2, 3, 5, 6, 10, 15, 30

30 has 8 factors in total.

3 of the factors have 2 digits.

Probability is number of desired outcomes/number of total outcomes.

We have 3 desired outcomes and 8 total outcomes.

Therefore, the probability that the factor chosen at random will have 2 digits is 3/8.
