Question

The null and alternative hypotheses for a population proportion, as well as the sample results, are given. Use StatKey or other technology to generate a randomization distribution and calculate a p-value. StatKey tip: Use "Test for a Single Proportion" and then "Edit Data" to enter the sample information.

Hypotheses: H0:p=0.5 vs Ha:p<⁢0.5;
Sample data: p^=38100=0.38 with n=100

Round the p-value to three decimal places.

**Chapter 4, Section 2, Exercise 060**

The null and alternative hypotheses for a population proportion, as well as the sample results, are given. Use StatKey or other technology to generate a randomization distribution and calculate a *p*-value. StatKey tip: Use "Test for a Single Proportion" and then "Edit Data" to enter the sample information.

**Hypotheses:**

$ H_0 : p = 0.5 $ vs $ H_a : p < 0.5 $;

**Sample data:**

\[
\hat{p} = \frac{38}{100} = 0.38 \text{ with } n = 100
\]

Round the *p*-value to three decimal places.

\[
p\text{-value} = \underline{\hspace{3cm}}
\]

The absolute tolerance is +/-0.005
