A teacher wants to compare the mean geology scores of two different classes. She is testing the null hypothesis that there is no difference in the population mean scores of the two classes. The difference of the sample means is 51.4. If the standard deviation of the distribution of the difference of sample means is 16.66, what is the 95% confidence interval for the population mean difference? A. between -33.2 and +33.2 B. between -49.9 and +49.9 C. between -102.8 and +102.8 D. between -154.2 and +154.2

Answers

Answer:

Standard deviation(S.D) = √{Mean difference(D²) - Mean(M)}

S.D.= 16.6

Step-by-step explanation: A) M =33.2

∴ S.D = √D² - 33.2

16.66 = √D² - 33.2

D² = 16.66² + 33.2 = 277.56 - 33.2 = 244.36

∴D = √244.36 = 15.6

B) M= 49.9

∴ S.D.=√D² + 49.9

 16.6 =√D² + 49.9

 D² = 16.6² + 49.9 = 277.56 + 49.9 = 327.46

∴ D = √327.46 = 18.1

C) M = 102.8

∴ S.D. =√D² + 102.8

16.66 =√D² + 102.8

D² = 16.66² + 102.8 = 277.56 + 102.8 =  380.36

∴ D =√380.36 = 19.5

D) M = 154.2

∴ S.D. = √D² + 154.2

16.66 =√D² + 154.2

D² = 16.66² + 154.2 =277.56 + 154.2 = 431.76

D =√431.76 = 20.8

Which option is a function

Answers

(x,y)
for every x there is exatly 1 y
basically, x never repeats with a differnt y

first one works, no x's repeart

2nd is not, 1 repeats wwth 9 and -4

3rd is correct

4th is wrong, 0 repreats with 3 and 7

5th is correct



so the functions are 1st 3rd 5th

Which equation can be simplified to find the inverse of y = 5x2+10?A. x = 5y2 + 10
B. 1/y=5x^2+10
C. –y = 5x2 + 10
D. y= 1/5x^2+1/10

Answers

To find the inverse of a function, simply switch y with x:

So, y = 5x2 + 10 will become x = 5y2 + 10.

The correct option will therefore be A.

Answer:

I agree, it's also A.
