If we plug the values, we have
So, we have to solve the following equation:
So, when we impose 
, knowing the value of p, we have
And so the solution is
Answer is:
3
Step by step explanation:
2x-1=x+2
or, 2x-x=2+1
or, x=3
PQ = x+2
= 3+2
= 5

It would be best to draw the problem described above. Sketching it, you will see that a right triangle would be formed from the description where the vertical distance of the dog to its owner is the height of the triangle and the angle of elevation of the triangle would be 10 degrees. The hypotenuse of the triangle represents the distance of the dog from its owner. By using trigonometric functions, we can easily calculate for this value. We use the sine function which is equal to the opposite side divided by the hypotenuse.
sine 10 = 30 feet / hypotenuse
hypotenuse = 172.76 feet ( distance of the dog to its owner )
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
