ACTIVITY 1 Directions: State the null and alternative hypothesis on Population Mean 1. An average TV viewing of all five-year old children is 4 hours daily 2. A college librarian claims that 20 story books on the average are borrowed. 3. The mean performance of all grade 11 students of a school in the NAT is 35 Points to ponder: How can Activity 1 help you do the problem solving? Do you think that solving problem using the null and alternative hypothesis you to get the correct answer? YES, NO, IF NO state your reason ACTIVITY 2 Directions: Decide whether a test is two tailed or one tailed test, 1. A nutritionist claims that her developed bread is fortified with vitamin B 2. A musician believes that listening to classical music affects mood 3, a storekeeper thinks that time of day influences sales of ice cream ACTIVITY 1 Directions: Solve problems involving test of hypothesis on the population mean by supplying the solutions on the table 1. A soda manufacturer is interested in determining whether its bottling machine tends to overfill. Each bottle is supposed to contain 12 fluid or. A random sample of 52 bottles was taken and found that the mean amount of soda of the sample of bottles is 12.1 fl oz with a standard deviation of 0.2 fl oz. If the manufacturer decides on a level o.05 test, should the null hypothesis be rejected? Belat 1, Formulate the null and alternative hypothesis 2. Choose a significance level and the test statistic to be used 3. Determine if it one tailed or two failed and establish the critical value 4, Compute for the test statistic using data from the population and the sample 5.Make decision "If the computed value of the test statistic is greater than the critical value reject the null "If the computed value of the test statistic is lower than the critical value accept the mill 6. State the conclusion Points to ponder: Where do you think does the mean of probability distribution is applicable in your daily situation
