Answer:
Option C
Step-by-step explanation:
Option C would map (1,3) to (-1,4).
1 - 2 = -1
3 + 1 = 4
Option C should be the correct answer.
Answer:
Pvalue = 0.1505
y = 0.550x1 + 3.600x2 + 7.300
Step-by-step explanation:
Given the data :
Study Hours GPA ACT Score
5 4 27
5 2 18
5 3 18
1 3 20
2 4 21
Using technology, the Pvalue obtained using the Fratio :
F = MSregression / MSresidual = 30.228571/ 8.190476 = 3.69
The Pvalue for the regression equation is:
Using the Pvalue from Fratio calculator :
F(1, 3), 3.69 = 0.1505
Using the Pvalue approach :
At α = 0.01
Pvalue > α ; Hence, we fail to reject H0 and conclude that ; There is not enough evidence to show that the relationship is statistically significant.
The regression equation :
y = A1x1 + A2x2 +... AnXn
y = 0.550x1 + 3.600x2 + 7.300
x1 and x2 are the predictor variables ;
y = predicted variable
650 is your answer because you have ti take away the zeros
The null hypothesis is p = 0.68 while the alternative hypothesis will be that it's below that is p < 0.68.
First, let us understand the Null and Alternative hypotheses:
The null hypothesis is simply to predict that there is no effect of the relationship between the variables.
The alternative hypothesis is to state the research prediction of a relationship or effect. In this case, the newsletter publisher believes that below 68% of their readers own a Rolls Royce.
The null hypothesis is that the proportion of readers who own a Rolls Royce is equal to 0.68.
Null hypotheses = H₀: p = 0.68
The alternate hypothesis is that the proportion of readers who own a Rolls Royce is below 0.68.
Alternate hypotheses = H₁: p < 0.68.
Thus, the null hypothesis is p = 0.68 while the alternative hypothesis will be that it's below that is p < 0.68.
