The score, 78, is the point estimate for the population mean test score, μ{“version”:”1.1″,”math”:”\mu “}

State the claim mathematically. Is the claim the null or alternative hypothesis?

The claim, mathematically, is p=0.50{“version”:”1.1″,”math”:”p=0.50″}

State the standardized test statistic. Justify by formula or stating the input to your calculator.

We would use the Student t distribution to construct our confidence interval. 

Determine the test of significance (t-test or z-test) and justify your choice.

The claim, written mathematically, is μ>13.5{“version”:”1.1″,”math”:”\mu>13.5″}

The claim is the alternative hypothesis.

Sketch a scatter plot for the data.  You may either attach your sketch by hand our your output from StatCrunch.

Determine the test of significance (t-test or z-test).
