Answer:
78
Step-by-step explanation:
The IQR is quartile 3 - quartile 1. First, we need to find the mean of the dataset, which is 50 -- the fifth number. Then, the median of the dataset on the left of the fifth number is the first quartile, and the median of the dataset on the right is the third. We get Q1 to then be halfway between 30 and 50, or 40, and Q3 to be halfway between 56 and n, so Q3 = (56+n)/2. Since we need Q3-Q1=27, or (56+n)/2-40=27, we have (56+n)/2=67 and 56+n=134, so n = 134-56=78
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.
