10 points Save Answe uestion 3 The recommended dietary allowance (RDA) of vitamin C for women is 75 milligrams (mg) per day. A hypothesis test, with a significance level of 0.05, is to be performed to decide whether adult women are, on average, getting less than the RDA of 75 mg per day. A researcher gathers data from a random sample of women in order to carry out the test. Based on this data, she calculates a test statistic of t 2.207 and a P-Value of 0.0178. Based on the sample results and at a 0.05 significance level she should OReject Ho There is sufficient evidence that adult women do get less than the RDA of 75 mg per day OReject Ho There is not sufficient evidence that adult women do get less than the RDA of 75 mg per day OFail to reject Ho There is sufficient evidence that adult women do get less than the RDA of 75 mg per day Fail to reject Ho There is not sufficient evidence that adult women do get less than the RDA of 75 mg per day Moving to the next question prevents changes to this answer.
