this is the question

20. (10pt) 64 of 106 randomly selected shoppers believed \"Made in the USA\" means 100% of labor andmaterials are from the United States. Let p represent the true proportion of consumers who believe \"Made in the USA\" means 100% of labor and materials are from the United States. A claim is made that p = 0.7, consider testing Ho : p = 0.7 against Ha : 19 7E 07. a. Calculate a point estimate for p. b. Calculate the test statistic for the test. Make the appropriate conclusion using the test statistic and the rejection region (or critical value) using a = 0.01. c. Find the pvalue for the test and make the appropriate conclusion using pvalue
