Question

Television Survey In a recent survey, it was stated that Americans watch television on average four hours per day. Assume that o = 2. Using your class as the sample, conduct a hypothesis test to determine if the average for students at your school is lower 1. Ho: 2. H 3. In words, define the random variable. 4. The distribution to use for the test is S. Determine the test statistic using your data. 6. Draw a graph and label it appropriately.Shade the actual level of significance. a. Graph: Figure 5.21 b. Determine the p-value 7. Do you or do you not reject the null hypothesis? Why? 8. Write a clear conclusion using a complete sentence. Language Survey About 42.3% of Californians and 19.6% of all Americans over age five speak a language other than English at home, Using your class as the sample, conduct a hypothesis test to determine if the percent of the students at your school who speak a language other than English at home is different from 42.3%

Answer 1

Solution Tebwilion Survey Hi= u<4 [thy H. = 4 = 4 (Americans watch the tilvision on an average you, sowie watch on an arrage less than 4 hours Let X be the random variable The distribution to the for the test is Reifen distribution because a rate is giver Iday P(x)= Let the no. Students in the clefs be del =e-4 45 5! = 0.1563 The value of the peiller distraliter at = 4 il = 0.78513 :. We do not reject the nelle hypothesis and 1-5

Jeans's Surrey H. = 4 = 3 (adults have 3 Jeans on an average) Hi = 3 Cadults have more than 3 years) Hot X be the random werigble The distribution is poisson distribution P(x)=e-u un The ne of people for turvey = 8 = e-338 -0.008115 The value of the haillen distribution = 0.99620 at n=8 and l=3 We do not reject the rell hypothesis All = adults have Jeans on an antage

Whenever a rate of something happening is given we use the poisson distribution.

Example of rate of something- 5 cars coming at a signal in every 2 minutes. So the rate become 5cars/2 minutes.

Thanks.
