Answer:
40
Step-by-step explanation:
4x
4(10)
Answer:
(x+2)(x+5) or if you were looking for the x-intercepts they would be -5, and -2
Answer:
560 cubic inches
Step-by-step explanation:
Substitute:
V = lwh
V = 4(10)(14)
V = 40(14)
V = 560 in^3
The appropriate statistical procedure to use here is a two-tailed hypothesis test for the population mean
What is standard deviation?
- The term "standard deviation" (or "σ") refers to a measurement of the data's dispersion from the mean.
- A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.
Explanation:
- Since we are interested in comparing here the mean heart rate for Canadians who participated in this fitness program, to that of the national average,
- We have to have to conduct a hypothesis test here for sample mean
- Since we are not trying to find the true population mean based on the sample mean, we do not have to construct a confidence interval
- As the sample size, n = 26 < 30,therefore we will use the t-test instead of the z-test.
Therefore, A one-sample t-test for means' is the correct choice.
