Answers | A+ Score Assured
The multiple linear regression equation ŷ = 6 + 1.9x1 + 2x2 - 5x3 has (n-3)
degrees of freedom. - 🧠ANSWER ✔✔False
A marketing research firm is planning a study to test whether the market
share that a new product will capture during its first year on the market is at
most 20 percent. After setting up the null and alternative hypotheses, the
appropriate alternative hypothesis would be that the market share
percentage is: - 🧠ANSWER ✔✔Greater than 20%
A correlation coefficient is an absolute measure. - 🧠ANSWER ✔✔False
,In a simple linear regression analysis, the p-value associated with a test of
the slope coefficient was equal to .035, which would lead us to do what at
the 5% level of significance? - 🧠ANSWER ✔✔Conclude that the true slope
for the population is not equal to zero.
In forecasting the trend in sales from time series data with a simple linear
regression equation, the dependent variable would be time, since sales
would depend upon the time period used. - 🧠ANSWER ✔✔False
If a p-value in Excel is 8.4298E-142, that p-value is - 🧠ANSWER ✔✔a very
small positive number.
A correlation coefficient of -1.0 would imply that the standard error of the
estimate (Se) would necessarily be equal to zero.
Correct Answer - 🧠ANSWER ✔✔True
In an upper-tailed test of the difference of two proportions, the z-value was
calculated to be 1.20. The p-value for this test would then be .1151. -
🧠ANSWER ✔✔True
A sporting goods company is testing two carriers to determine which
company should deliver its packages. The company wants to test if Carrier
, 2 has faster shipping times. Packages were shipped to 36 locations using
each of the carriers. The results are as follows:
Carrier 1: mean delivery time = 14 hours, s = 3.1 hours, n = 36
Carrier 2: mean delivery time = 13 hours, s = 2.6 hours, n = 36
Difference (Carrier 1 time - Carrier 2 time): mean = 1 hour, s = 2.9 hours, n
= 36
The correct t-value for this question is: - 🧠ANSWER ✔✔2.07
When an analyst accepts the null hypothesis that the population slope is
equal to zero, the conclusion is that the X variable is a statistically
significant predictor. - 🧠ANSWER ✔✔False
Assume for a given hypothesis testing problem, the test statistic was
computed and led to an acceptance of the null hypothesis at the .10 level of
significance. Based on this information, we can further conclude that since
H0 was accepted at the 10% level, then H0 - 🧠ANSWER ✔✔must be
accepted at the 1% level of significance AND accepted at the 5% level of
significance.
