Enjoy the latest technologies and s to your favorite apps Scenario #3. Say that you know that the average amount of time that an adult can concentrate on reading a text is 30 minutes, and you want to test a manufacturer's claim to see if a new protein drink can make a significant difference in people's concentration. collect a sample of 9 subjects, give them each the protein drink, and discover that your sample has an average concentration time of 26 minutes, with a standard deviation of 6 minutes. Did the protein drink make a significant difference in their concentration time? Test ato = .05 Now you need to complete the hypothesis test: Step I:Choose which of the following is the correct symbolic version of the hypotheses 2 points Save QUESTION 18 ario # 3. Say that you know that the average amount of time that an adu ult can concentrate on reading a text is 30 minutes, and you Scena want to test a collect a sample of 9 subjects, give them each the acturer's claim to see if a new protein drink can make a significant difference in people's concentration.

Explanation / Answer

Here we are supposed to test:x

We have given following data:

Sample size = n = 9

Sample mean = = 26

Sample standard deviation = s = 6

We are supposed to consider level of significance as 5%

The test statistic for this test is given as:

P-value is given as:

P(>2) = 0.0805 …. From t-distribution table

Observe that the p-value is greater than level of significance, hence we can reject Ho and we can conclude that protein drink does not make significance difference in concentration time.
