Rhino viruses typically cause common colds. in a test of the effectiveness of echinacea, 46 of the 51 subjects treated with echinacea developed rhinovirus infections. in a placebo group, 82 of the 95 subjects developed rhinovirus infections. use a 0.01 significance level to test the claim that echinacea has an effect on rhinovirus infections. complete parts (a) through (c) below.test the claim using a hypothesis test. consider the first sample to be the sample of subjects treated with echinacea and the second sample to be the sample of subjects treated with a placebo. what arc the null and alternative hypotheses for the hypothesis test? identify the test statistic. - (round to two decimal places as needed.) identify the p-valuc. (round to three decimal places as needed.) what is the conclusion based on the hypothesis test? what is the conclusion base

It is very important to look at all the information's that are given in the question. these information's will in getting to the desired result.
initial number = 24
final number = 30
amount of increase = 30 - 24
                                  = 6
then
percentage increase = (6/24) * 100
                                    = 100/4 percent
                                    = 25 percent
so the percentage of increase is 25%. i hope the procedure is clear enough for you to understand. you can use this method for solving similar type of problems in future without requiring any from outside.
