# HW06: Hypothesis Test for a Single Mean

Due date: 2022-10-28

Use the dataset penguins. Download the data and save the CSV file into your HW06 directory (so that it is submit when you upload your HW06 folder).

Read the help file about penguins, to better understand the data set.

Please submit a folder containing your Quarto input (qmd) and output (html) documents for this lab, named `HW06`

, to our shared Google Drive folder when you are finished.

Pick a numeric variable of your choice and use it for the rest of this assignment. No code needed here.

Make a histogram of your numeric variable and describe its shape.

Perform a hypothesis test of your numeric variable against a value of your choice, using \(\alpha = 0.02\). Please state your hypotheses.

Based on your test, which hypothesis is more likely given the data? State your conclusion as either “reject H0” or “fail to reject H0”, and explain why this conclusion is appropriate.

Interpret in context of the data your conclusion of the hypothesis test.

Interpret, in context of the data, the confidence interval that appropriately matches your hypothesis test above.

Pick a value for which you are guaranteed to reject the null hypothesis, H0. Justify your conclusion by updating your

`t.test(...)`
