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

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

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″}

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

The claim is the alternative hypothesis.

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

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

State the null and alternative hypotheses. Write your answers as “H_0: answer” and “H_a: answer”
