Type of Medicine A medical researcher wishes to determine if the type of vitamin pills taken is related to the age of the person. The data are shown. At $\alpha = 0.05$, is the type of vitamin related to the age of the person taking the vitamin? Use the $P$-value method with a graphing calculator. Age Liquid Tablet Gummy 20-39 5 10 19 40-59 18 27 7 60-over 5 10 4 Send data to Excel Part: 0 / 4 Part 1 of 4 (a) State the hypotheses and identify the claim with the correct hypothesis. $H_0$: The type of vitamin pill is independent of the age of the person taking the pill. Not claim $H_1$: The type of vitamin pill is dependent on the age of the person taking the pill. Claim Part: 1 / 4 Part 2 of 4 (b) Find the $P$-value. Round the answer to at least four decimal places.
