Question
![**Hypothesis Testing on Organizational Strategy**
A consulting group conducted a global survey of product teams to understand better the dynamics of team performance and successful practices. The survey found that 33% of organizations have a coherent business strategy they adhere to and communicate effectively. To validate this finding, another study is proposed to prove the percentage is less than 33%. Complete parts (a) and (b) below.
**a. State the null and research hypotheses.**
Identify the null and alternative hypotheses.
- A. \( H_0: \pi \geq 0.33; \, H_1: \pi < 0.33 \)
- B. \( H_0: \pi \leq 0.33; \, H_1: \pi > 0.33 \)
- C. \( H_0: \pi = 0.33; \, H_1: \pi \neq 0.33 \)
- D. \( H_0: \pi = 0.33; \, H_1: \pi \neq 0.33 \)
**b. A sample of 100 organizations is selected**, and results indicate that 32 organizations have a coherent business strategy that they stick to and effectively communicate. Use the p-value approach to determine at the 0.01 level of significance whether there is evidence that the percentage is less than 33%.
Calculate the test statistic.
The test statistic, \( Z_{STAT} \), is \( \Box \).
(Type an integer or a decimal. Round to two decimal places as needed.)
Calculate the p-value.
The p-value is \( \Box \).
(Type an integer or a decimal. Round to three decimal places as needed.)
State the conclusion of the test.
\[ \Box \] the null hypothesis. There is \( \Box \) evidence to conclude that the percentage of organizations which have a coherent business strategy that they stick to and effectively communicate is less than 33%.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0a63f6a7-ec54-4c0e-abf5-810ded572838%2Fbe4b2d54-97e6-47f2-a236-043ed920237e%2F6o4toqq_processed.png&w=3840&q=75)
