Answer:
The test statistic for this hypothesis test is - 3.68.
Explanation:
A test statistic is a random variable that is calculated from sample data and used in a hypothesis test. You can use test statistics to determine whether to reject the null hypothesis. The test statistic compares your data with what is expected under the null hypothesis.
Sample proportion = 38/50
= 0.76
Hence,
Test statistic
![= \frac{0.76-0.50}{\sqrt{0.50*0.50/50}}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B0.76-0.50%7D%7B%5Csqrt%7B0.50%2A0.50%2F50%7D%7D)
= 3.68
