Question 1

Suppose I have the following hypotheses:

• Null hypothesis: Customer satisfaction with the service speed and customer satisfaction with the food quality at Valentino's are not correlated.
• Alternative hypothesis: Customer satisfaction with the service speed and customer satisfaction with the food quality at Valentino's are correlated.

Use a significance level of 0.05.

1. What is the correlation coefficient between customer satisfaction with the service speed (SS_Valentinos) and customer satisfaction with the food quality (FQ_Valentinos) at Valentino's? Round your answer to two decimal places.
2. What is the t statistic for the correlation's significance? Round your answer to two decimal places.

2.3 What is your conclusion? Remember, you need the p-value of the t statistic to determine this.

cannot reject the null hypothesis

reject the null hypothesis

2.4 What does your conclusion mean?

We can state with a 0.05 significance level that there is no correlation between customer satisfaction with the service speed and customer satisfaction with the food quality at Valentino's.

We can state with a 0.05 significance level that there is a correlation between customer satisfaction with the service speed and customer satisfaction with the food quality at Valentino's.
