Question
A furniture company wants to know what percent of their customers are satisfied with the furniture they purchase. The company surveys 153 customers to gather feedback. Suppose that, in reality, 91% of all customers are satisfied with their purchase. 1. **How are the collection of all sample proportions of samples of size 153 distributed?** - Normally distributed with a mean (\(\mu\)) of 0.91 and a standard deviation (\(\sigma\)) of 0.0231. 2. **What is the probability that fewer than 88% of those surveyed are satisfied with their purchase?** - **List the z-scores needed to calculate the result:** \(-1.30\) - There is a 9.68% chance that fewer than 88% of those surveyed are satisfied with their purchase. 3. **What is the probability that more than 92% of those surveyed are satisfied with their purchase?** - **List the z-scores needed to calculate the result:** \(0.43\) - There is a 33.36% chance that more than 92% of those surveyed are satisfied with their purchase. 4. **What is the probability that between 88% and 92% of those surveyed are satisfied with their purchase?** - **List the z-scores needed to calculate the result:** \(0.43\) - There is a 33.36% chance that between 88% and 92% of those surveyed are satisfied with their purchase. **Submit Question**
