Achi square test has been conducted to assess the relationship between marital status and church attendance. the obtained chi square is 23.45 and the critical chi square is 9.488. what may be concluded?
a. reject the null hypothesis, church attendance and marital status are dependent
b. reject the null hypothesis, church attendance and marital status are independent
c. fail to reject the null hypothesis, church attendance and marital status are dependent
d. fail to reject the null hypothesis, church attendance and marital status are independent

 a. reject the null hypothesis, church attendance and marital status are dependent

Step-by-step explanation:

Given : A Chi square test has been conducted to assess the relationship between marital status and church attendance. The obtained Chi square is 23.45 and the critical Chi square is 9.488.

Null hypothesis : There is no relationship between the variables.

Alternative hypothesis : There is a relationship between the variables.

Here we can see that the obtained chi-square (23.45) value is greater than the critical chi square value (9.488) , then we have to reject the null hypothesis.

So the correct answer is reject the null hypothesis, church attendance and marital status are dependent.

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
