  The total population of the age recorded was 1000, while those of highest school grade complete was 989.

  4

  The people had a mean age of 36.637 and a standard deviation of 6.199.

  This shows that most people deferred from the mean by up to 6.199 difference (George et al.

  2016).

  The variable of the highest grade complete is 11.28, with a small standard deviation of 1.56.

  On the race and ethnicity variable, the black and not Hispanic are 803, which is 80.3% of the population while Hispanic, where 128 which is 12.8%, whites and not Hispanic were 53 which is 5.3% and others, were 14 which is 1.4% of the population.

  On the currently employed variable, 452 were employed, which is 45.2%of the population, and 456 were not employed, which is 45.6% of the population.

  Compute a 95% confidence interval around the mean. (Use 1.96 for the 95% CI and get the standard error from the descriptive statistics table). You should get a range (2 numbers) for the salary. The formula is as follows: 95% CI = [mean ± (1.96 SE)] ___95% CI = (1720.95 to 1824.226) ___

  Compute a 99% confidence interval around the mean. (Use 2.58 for the 99% CI and get the standard error from the descriptive statistics table). You should get a range (2 numbers) for the salary. The formula is as follows:

  99% CI = [mean ± (2.58 SE)] ____99% CI = 1704.62 to 1840.56___

  Which interval is wider?

  Explain.

  8

  The 99% CI interval is wider.

  This is because when the confidence interval gets higher, the range widens to increase the probability of the mean falling within it (George et al.

  2016)
