Answer:
C) If the null hypothesis were true, there is a 2 percent chance of obtaining a chi-square value of at least 7.82.
Step-by-step explanation:
The value of the chi-square test statistic was 7.82 and the p- value is 0.02. This means that if the null hypothesis were true there is a 2 percent chance of obtaining a chi square value of at least 7.82
The p- value is defined as obtaining the test statistic under H0 as extreme as observed.
When the p- value is less than 0.05 in the chi square goodness fit test it means that the null hypothesis is rejected.
There fore option C is the best answer.
A)There is a 2 percent chance that the company's claim is correct.
B) There is a 2 percent chance of obtaining a chi-square value of at least 7.82.
C) If the null hypothesis were true, there is a 2 percent chance of obtaining a chi-square value of at least 7.82.
D) If the null hypothesis were true, there is a 2 percent chance that the company's claim is correct.
E) If the null hypothesis were true, there is a 2 percent chance of obtaining a chi-square value of 7.82.
Answer:
x = 71
Step-by-step explanation:
18(x + 1) = -54
to start off, subtract 18 from both sides
18 - 18(x + 1) = -54 - 18
that should give you
x + 1 = 72
(its safe to take out paranthesis from problem by now) now take away 1 from each side
x + (1 - 1) = 72 - 1
that should give you
x = 71
-2/5x -2= 18
-2/5x=18+2
Divide -2/5 with both sides
x= -50
