mr Goodwill [35]2 years ago

Answer:

1.67 people per minute

Step-by-step explanation:

it's a proportion, basically. 5/3 = x/1, solve and you get 1.67. BTW if only five people enter in the span of 3 minutes, then this store needs to invest in advertising more, because i've seen CVS's with a better ratio than that. and that's sad!

The difference between the sample statistic and population parameter is called:_______
myrzilka [38]

Answer:

The difference between the sample statistic and population parameter is called sampling error.

Step-by-step explanation:

We are given the following in the question:

  • A sample is a part of population, it is a subset of population.
  • A sample statistic describes the sample. It is a characteristic of sample and different from the population.
  • A parameter describes the population. It is characteristic of a population.
  • A sample may not be able to represent the whole population and this may lead to error.
  • Thus, sampling error is the difference between the sample statistic and population parameter.
  • It arises when the sample is not able to describe the population.

The difference between the sample statistic and population parameter is called sampling error.

Doing so leads to the answer [3   -12    15    -21]

Side note: I'm assuming the matrix given to you has 1 row and 4 columns.

Vadim26 [7]

Answer:

The 98% confidence interval for the mean number of hours of study time per week for all students is (20.9, 25.1).

Step-by-step explanation:

Confidence interval:

Sample mean plus/minus the margin of error.

In this question:

Mean of 23.

Margin of error 2.1.

Then

23 - 2.1 = 20.9

23 + 2.1 = 25.1

The 98% confidence interval for the mean number of hours of study time per week for all students is (20.9, 25.1).
