Answer:
those that use both soaps= 15 households
Explanation:
From the survey households use the following:
Neither soap A nor B= 80
So those that use soap= 200- 80= 120
Only soap A= 60
So those that use only soap B or both= 120- 60= 60
For every household that used both brands of soap, 3 used only Brand B soap.
So assume out of 4 households 1/4 use both soaps, and 3/4 use soap B
Therefore those that use both soaps= (1/4)*60
= 15 households

Answer:
The correct answer is a) distributional.
Explanation:
The standard error is the standard deviation of the sample distribution of a sample statistic.1 The term also refers to an estimate of the standard deviation, derived from a particular sample used to compute the estimate.
The sample mean is the usual estimator of a population mean. However, different samples chosen from the same population tend in general to give different values of sample means. The standard error of the mean (that is, the error due to the estimation of the population mean from the sample means) is the standard deviation of all possible samples (of a given size) chosen from that population. In addition, the standard error of the mean can refer to an estimate of the standard deviation, calculated from a sample of data that is being analyzed at the same time.
