In 1997 the interest category for 12% of all new magazines was sports. This describes a parameter. True or false
algol13
False ....a parameter is something YOU can change, like asking magazines if they are interested in sports, or interested in photography, or something else. So the 12% is a statistic.

You select a random sample of n=14 families in your neighborhood and find the following family sizes (number of people in the fa
satela [25.4K]

Answer:

a. Best estimate for the mean family size for the population of all families in a country is 16.3571428571

b. 95% confidence interval for the estimate is 16.3571428571±0.7106240840. That is between 15.6465187731 and 17.0677669411

c. The sample is unlikely to be very representative of all families in a country.

Step-by-step explanation:

a. mean family size for the population of all families in a country can be estimated as sample mean, and calculated as:

\frac{15+ 16+ 19+ 18+ 17+ 15+ 16+ 16+  15+ 16+  15+ 16+ 17+ 18 }{14} ≈ 16.3571428571

b. 95% confidence interval for the estimate can be calculated using the equation CI=M± \frac{t*s}{\sqrt{N} } where

  • M is the mean estimate (16.3571428571)
  • t is the corresponding statistic in the 95% confidence level and with 14 degrees of freedom (2.160)
  • s is the standard deviation of the sample (1.2309777100)
  • N is the sample size (14)

s can be calculated as square root of mean squared differences from the sample mean.

Thus 95% CI=16.3571428571± \frac{2.160*1.2309777100}{\sqrt{14} } ≈ 16.3571428571±0.7106240840

The sample is unlikely to be very representative of all families in a country because as the sample data increases, estimate will improve.
