Math Problem Statement

Test the hypothesis using the P-value approach: H0: p = 0.59 versus H1: p < 0.59, n = 150, x = 81, α = 0.01.

Solution

The image contains a hypothesis test scenario where the P-value approach is being used. Here's a breakdown of the information:

  • Null hypothesis H0H_0: p=0.59p = 0.59
  • Alternative hypothesis H1H_1: p<0.59p < 0.59
  • Sample size nn: 150
  • Number of successes xx: 81
  • Significance level α\alpha: 0.01

Additionally, the condition to verify if the normal approximation can be used is checked:

  • The condition np0(1p0)10np_0(1 - p_0) \geq 10 has been met.

The technology-based calculation of the P-value is provided:

  • P-value = 0.208, rounded to three decimal places.

Conclusion:

Given that the P-value (0.208) is greater than the significance level α=0.01\alpha = 0.01, we do not reject the null hypothesis. This means there is not enough evidence to conclude that the true proportion is less than 0.59 at the 1% significance level.

Here are 5 related questions to expand your understanding:

  1. What is the interpretation of the P-value in hypothesis testing?
  2. How is the test statistic calculated for a proportion hypothesis test?
  3. Why is the condition np0(1p0)10np_0(1 - p_0) \geq 10 important for using the normal approximation?
  4. How would the conclusion change if the significance level α\alpha were higher (e.g., 0.05)?
  5. What are the steps for manually calculating the P-value without technology?

Tip: Always compare the P-value with the significance level α\alpha to decide whether to reject or fail to reject the null hypothesis.
