Answer:
Option 2
Step-by-step explanation:
1.621 kN
Step-by-step explanation:
Let the centerline of the canal be the x-axis. Because the forces exerted by the horses are symmetric to the centerline, only the x-components of these forces contribute to the resultant force on the barge, i.e., the y-components cancel out. Each x-component is equal to = 810.4 N. Therefore, the resultant force on the barge is twice this:
Answer: The critical value is: insufficient.
Step-by-step explanation: Refer to Exhibit 9-2. The p-value is:
a. .0500
b. .0228
c. .0456
d. .0250
In order to test the hypotheses H0: μ ≤ 100 and Ha: μ > 100 at an α level of significance, the null hypothesis will be rejected if the test statistic z is:
The practice of concluding "do not reject H0" is preferred over "accept H0" when we:
a. have an insufficient sample size.
b. have not controlled for the Type II error.
c. are testing the validity of a claim.
d. are conducting a one-tailed test.
In hypothesis testing, the critical value is: insufficient
