Question

Write an APA style report that summarizes all of your findings. Your report should include each of the following, with no errors of APA style and formatting. Round p-values to three decimal places; all other measures to two.

a) descriptive statistics for each trait in your sample, and for the population b) the value of the test statistic c) the precise p-value, ex. not p < .05 but p = .015, unless reports p = .000, in which case you must use p < .001

d) a clear statement of the findings: If the findings are significant, your report should write about these in terms of the direction of differences, e.x. “The elderly are significantly higher in Extraversion than the general population.” rather than “The elderly showed significant differences in Extraversion from the general population.”

Otherwise, your report should state that there was no significant difference.

Information:

Population mean = 30, population standard deviation=6, sample mean = 28.80, sample size n=20

The significant level alpha is 0.05, the critical value for 2 tailed test is critical z =1.96

Test statistic: z= 28.80 – 30/ (6/ sqrt 20) => z= -0.894

There is not enough evidence to claim that the population mean is different than 30 at the 0.05 significance level.

p value = 0.3711

Please provide a step by step as per requirements.
