Transcribed Image Text:### Test the Claim of Trydint Bubble-Gum Company
"Trydint" bubble-gum company claims that 3 out of 10 people prefer their gum to "Eklypse". Test their claim at the 90% confidence level.
#### Hypothetical Testing
The null and alternative hypothesis in symbols would be:
- \( H_0 \): \( p \leq 0.3 \)
- \( H_1 \): \( p > 0.3 \)
- \( H_0 \): \( \mu = 0.3 \)
- \( H_1 \): \( \mu \neq 0.3 \)
- \( H_0 \): \( \mu \geq 0.3 \)
- \( H_1 \): \( \mu < 0.3 \)
- \( H_0 \): \( p \leq 0.3 \)
- \( H_1 \): \( p > 0.3 \)
- \( H_0 \): \( p \geq 0.3 \)
- \( H_1 \): \( p < 0.3 \)
- \( H_0 \): \( p = 0.3 \)
- \( H_1 \): \( p \neq 0.3 \)
#### Null Hypothesis in Words
The null hypothesis in words would be:
- The proportion of people in a sample that prefers Trydint gum is 0.3.
- The average of people that prefer Trydint gum is not 0.3.
- The proportion of all people that prefer Trydint gum is greater than 0.3.
- The proportion of all people that prefer Trydint gum is less than 0.3.
- The average of people that prefer Trydint gum is 0.3.
- The proportion of people in a sample that prefer Trydint gum is not 0.3.
- The proportion of all people that prefer Trydint gum is 0.3.
#### Calculation Based on Sample Data
Based on a sample of 80 people, 19 said they prefer "Trydint" gum to "Eklypse".
The point estimate is: \(\_\_\_\_\_\_\_\_\) (to 3 decimals)
The 90% confidence interval is: \(\_\_\_\_\_\_) to \(\_\_\
