“Data Analysis is Preparations:Describe sample summary statistics.provide a histogram and summary, check assumptions, and find the test” statistic and significance level.
“o Provide the descriptive statistics (sample size,mean.median.and standard deviation).”
o Provide a histogram of your sample.
“o Describe your sample by writing a sentence describing the shape.center,and spread of your sample.”
o Determine whether the conditions to perform your identified test have been met
• Calculations:Calculate the value.describe the p value and test statistic in regard to the normal curve graph.discuss how the pvalue relates
to the significance level.and compare the pvalue to the oversimplification reject or failto reject the null hypothesis.
o Determine the appropriate test statistic. then calculate the test statistic.
Note:
This calculationis (mean – target)/stanclard error.Inthis case.the meanis your regional mean (Pacific).and the target is 275.
o Calculate the pvalue.
“Note:For right-tailed.use the T.DIST.RT functionin Excel.left-tailedis theT.DIST function, and two-tailedis the T.DIST.2T function.The”
degree of freedom is calculated by subtracting 1from your sample size. Chooseyour test from the fol owing:
-T.DIST.RT([test statistic].[degree of freedom])
;T.DIST((test statistic].[degree of freedom]. 1)
;T.DIST.2T((test statistic]. [degree of freedom])
“o Using the normal curve graph as a reference,describe where the pvalue and test statistic would be placed.”
• Test Dedsion:Discuss the relationship between the pvalue and the significance level.including a comparison between the two.and decide to
reject or failto reject the null hypothesis.
o Discuss how the pvalue relates to the significance level.
o Compare the pvalue and significance level. and make a decision to reject or failto reject the null hypothesis.
Conclusion: Discuss how your test relates to the hypothesis and discuss thestatisticalsignificance.
o Explain in one paragraph how your test decision relates to your hypothesis and whether your conclusions arc statistically significant.
