I need to preform a one sample t test on the data below.

The question: Is the Service Desk fulfilling its obligation to provide a significantly greater than 75% positive customer feedback?

I am comparing feedback with the mean of H1 = 75

.05 Alpha

The Data Set is below and randomly sampled 50 responses over the last 6 months.

True = Positive Customer feedback

False = Not positive feedback.
