1. The producer of the news station posted an article about the high school’s football championship ceremony on a new website. The website had 500 views after four hours. Create a table to show how many views the website would have had after the first, second, and third hours after posting, if the website receives views at the same rate. How many views would the website receive after 5 hours?2. Write an equation that represents the relationship from Problem 1. Do you see any connections between the equations you wrote and the ratio of the number of views to the number of hours?3. Use the table in Problem 1 to make a list of ordered pairs that you could plot on a coordinate plane.4. Graph the ordered pairs on a coordinate plane. Label your axes and create a title for the graph.5. Use multiple tools to predict how many views the website would have after 12 hours.

A local tennis pro-shop strings tennis rackets at the tension (pounds per square inch) requested by the customer. Recently a customer made a claim that the pro-shop consistently strings rackets at lower tensions, on average, than requested. To support this claim, the customer asked the pro shop to string 17 new rackets at 59 PSI. Upon receiving the rackets, the customer measured the tension of each and calculated the following summary statistics: sample mean = 56, standard deviation = 2.4 PSI. in order to conduct the test the customer selected a significance level of a = .05. Interpret this value.A. The probability of concluding that the true mean is less than 59 psi when in fact it is equal to 59 psi is only .05.B. The probability of concluding that the true mean is less than 59 psi when in fact it is equal to 59 psi is only .05.C. The smallest value of ? that you can use and still reject H0 is 0 .05.D. There is a 5% chance that the sample will be biased

A new cream that advertises that it can reduce wrinkles and improve skin was subject to a recent study. A sample of 50 women over the age of 50 used the new cream for 6 months. Of those 50 women, 44 of them reported skin improvement(as judged by a dermatologist). Is this evidence that the cream will improve the skin of more than 40% of women over the age of 50? Test using α=0.01. (a) Test statistic: z= (b) Critical Value: z∗= (c) The final conclusion is A. We can reject the null hypothesis that p=0.4 and accept that p>0.4. That is, the cream can improve the skin of more than 40% of women over 50. B. There is not sufficient evidence to reject the null hypothesis that p=0.4. That is, there is not sufficient evidence to reject that the cream can improve the skin of more than 40% of women over 50.
