answer : The researcher did not state that the p-value is conditional on the null hypothesis being true ( A )
Step-by-step explanation:
What is wrong with the researcher's interpretation is that the researcher did not state that the p-value is conditional on the null hypothesis being true.
The P-value is a required value when either rejecting or accepting the null hypothesis. and the researcher did not add the clause that the probability of getting a statistic > 1.92 provided the null hypothesis is assumed to be true
Answer:
There are 3 adult tickets and 7 child tickets
Step-by-step explanation:
You are very close.
Let x = the number of adult tickets
Let y = number of child tickets
24.95x+ 15.95y = 186.50
The total number of tickets is 10
x+y =10
Subtract y from each side
x+y-y = 10-y
x =10-y
Substitute this into the first equation
24.95x+ 15.95y = 186.50
24.95(10-y) +15.95y = 186.50
Distribute
249.5 - 24.95y +15.95y =186.5
Combine like terms
249.5 - 9y = 186.50
Subtract 249.5 from each side
249.5-249.5 - 9y = 186.50-249.5
-9y =-63
Divide each side by -9
-9y/-9 = -63/-9
y =7
Now we need to find x
x+y =10
x+7 =10
Subtract 7 from each side
x+7-7 =10-7
x =3

Answer:
The slope is 5/-2.
Step-by-step explanation:
Slope is y1-y2 over m1-m2 (rise over run). The first ordered pair is -2 (m1) and 11 (y1). We then subtract the second ordered pair (4 (m2) and -4 (y2)) from the first.
11 - (-4) = 11 + 4 = 15
-2 - 4 = -6
Remember, slope is rise over run (y over x), so the slope is 15/-6. Now, we must simplify. 15/-6 = 5/-2
Dean went wrong because he thought that slope was run over rise (x over y). If he had switched the two numbers, his answer would have been correct.
