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

Jan walks 2 miles at a constant rate of 3 miles per hour and then runs 1 mile at a constant rate of 8 miles per hour.
stealth61 [152]

Answer:

(a).4.36 mph

(b) No

Step-by-step explanation:

We are given that

Jan covered distance,s1 =2 miles

Speed of Jan, a=3 mph

s2=1 mile

b=8mph

a.

We have to find the Jan' s average speed for the entire trip.

Average speed =\frac{2ab}{a+b}

Using the formula

Average speed=\frac{2(3)(8)}{3+8}=4.36mph

b.

Average speed with two speed

Average of Jan’s two speeds

=\frac{a+b}{2}

=\frac{3+8}{2}=5.5 mph

4.36\neq 5.5

Hence, the average speed in part (a) is not equal to the average of Jan’s two speeds.
