in essence it's just asking on getting the equation of that line in more or less slope-intercept form, hmmm well, it's a line, so all we need is two points to get it, hmmm let's see let's use the starting point and terminal point, so we know it goes through the origin, (0,0) and also goes through (1, 0.7), let's change 0.7 to a fraction, so its 7/10, ok, let's use those two points from it.
Plz help due tomorrow

Answer:
A) Reject the null hypothesis
B) Reject the null hypothesis
C) Fail to reject the null hypothesis
D) Reject the null hypothesis
Step-by-step explanation:
A) We are given;
Ha: μ > μ_o (This is thus, a one-tail problem)
n = 11
T = 1.91
Using online p-value from t-score calculator as attached with a DF = n - 1 = 11 - 1 = 10, and t-value = 1.91, and significance level of 0.05, and 1 tail, we have;
The p-value is 0.042602
P-value is less than significance level, thus, we will reject the null hypothesis
B) We are given;
Ha: μ < μ_o (This is thus, a one-tail problem)
n = 17
T = -3.45
Using online p-value from t-score calculator as attached with a DF = n - 1 = 17 - 1 = 16, and t-value = 1.91, and significance level of 0.05, and 1 tail, we have;
The p-value is 0.001647
P-value is less than significance level, thus, we will reject the null hypothesis
C)We are given;
Ha: μ ≠ μ_o (This is thus, a two-tail problem)
n = 7
T = 0.83
Using online p-value from t-score calculator as attached with a DF = n - 1 = 7 - 1 = 6, and t-value = 0.83, and significance level of 0.05, and 2 tail, we have;
The p-value is 0.438308.
P-value is higher than the significance level, thus, we will fail to reject the null hypothesis.
D) We are given;
Ha: μ > μ_o (This is thus, a one-tail problem)
n = 28
T = 2.13
Using online p-value from t-score calculator as attached with a DF = n - 1 = 28 - 1 = 27, and t-value = 2.13, and significance level of 0.05, and 1 tail, we have;
The p-value is 0.021218
P-value is lower than the significance level, thus, we will reject the null hypothesis
P-value is lower than the significance level, thus, we will reject the null hypothesis.
