Question

During California's initial shelter-in-place order, the Solano County Chamber of Commerce believed that 74% of residents would return to dine-in restaurants once the order was lifted. A poll taken in July now finds that 79 of 111 Solano residents would return to a restaurant once restrictions were lifted.

3. The Chamber of Commerce says that people are now more reluctant to return to restaurant dining. Do you agree?

Answer 1

Given :

Number of sample = n = 111

Number of success = X = 79

Claim : The Solano County Chamber of Commerce believed that 74% of residents would return to dine-in restaurants once the order was lifted.

Hypothesis test :

The null and alternative hypothesis is

Ho : p = 0.74

Ha : p > 0.74

Sample proportion :
