following are the solution to this question:
Step-by-step explanation:
please find the given table in the attached file.
Its circulatory system point-slope type involves picking out the formula for two points. That marker shape is:
In measure the slope m, we will use both levels. Or get one of the levels of teleport plugged in for (both do not matter)
Phase 1: I can choose two points from a list for a calculation of m slope: (1, 22) and (3, 46)
The m slope =12
Phase 2: going to settle on one of the plug-in points for :
I get: y - 22 = 12 (x - 1) formulas 1 of
If you choose to answer throughout the form of the a slope instead of a point slope form, you must modify Equation 1 to come in the form of a slope intercept.
<h2><u>Answer with explanation</u>:</h2>
Let p be the population proportion of parents who had children in grades K-12 were satisfied with the quality of education the students receive.
Set of hypothesis :
Confidence interval for population proportion is given by :-
, where
n= sample size
= sample proportion
and is the two-tailed z-value for confidence level (c).
As per given ,
Sample size of parents : n= 1085
Number of parents indicated that they were satisfied= 466
Sample proportion :
Critical value for 90% confidence interval : ( by z-value table)
Now, the 90% confidence interval :
Thus , the 90% confidence interval: (0.4043, 0.4537).
Since 0.43 lies in 90% confidence interval , it means we do not have enough evidence to reject the null hypothesis .
i.e. We are have no evidence that parents' attitudes toward the quality of education have changed.
