Select one: O True O FalseA presidential candidate claims that the proportion of college students who are registered to vote in the upcoming election is at least 64%. Suppose that we want to sample a number of college students and carry out a hypothesis test to see if this daim may be refuted. State the null hypothesis H, and the alternative hypothesis H, that we would use for this test. H: 0 H;: 0 A OSO D=0A student majoring in Management who has passed the Business Statistics course suspects that the average price of lunch at the canteen has increased during the pandemic. Before the pandemic, the price for lunch he paid was $21, $22, $22.50, $23, $23.50.
