Answer:whats the question
Explanation:(pls dont report me as soon as u tell me the question i will edit my answer and answer correctly)
Answer:
(A) Yes, since the test statistic is in the rejection region defined by the critical value, reject the null. The claim is the alternative, so the claim is supported.
Step-by-step explanation:
Null hypothesis: The wait time before a call is answered by a service representative is 3.3 minutes.
Alternate hypothesis: The wait time before a call is answered by a service representative is less than 3.3 minutes.
Test statistic (t) = (sample mean - population mean) ÷ sd/√n
sample mean = 3.24 minutes
population mean = 3.3 minutes
sd = 0.4 minutes
n = 62
degree of freedom = n - 1 = 62 - 1 = 71
significance level = 0.08
t = (3.24 - 3.3) ÷ 0.4/√62 = -0.06 ÷ 005 = -1.2
The test is a one-tailed test. The critical value corresponding to 61 degrees of freedom and 0.08 significance level is 1.654
Conclusion:
Reject the null hypothesis because the test statistic -1.2 is in the rejection region of the critical value 1.654. The claim is contained in the alternative hypothesis, so it is supported.
The angle of a tangent and a radius is a right angle.
The missing length would be the hypotenuse. Use the Pythagorean theorem to solve.
X = SQRT(12^2 + 16^2)
X = SQRT(144 + 256)
x = SQRT(400)
X = 20
Answer:
Weight of cereal in box in pound is 1.32277 pound
Given that;
Weight of cereal in box = 600 grams
Find:
Weight of cereal in box in pound
Computation:
1 gram = 0.00220462 pound
So,
600 gram = 600 × 0.00220462 pound
600 gram = 1.32277
Weight of cereal in box in pound = 1.32277 pound
