Laura spends an average of 1.5 hours doing her homework. After organizing her desk, Laura thinks she will spend less time doing her homework. She wants to the test that claim. Please show ALL work and explanations! Thank You! A.)State the null hypothesis. B.)State the alternative hypothesis
t a nearby college, there is a school-sponsored website that matches people looking for roommates. According to the school's reports, 44% of students will find a match their first time using the site. A writer for the school newspaper tests this claim by choosing a random sample of 165 students who visited the site looking for a roommate. Of the students surveyed, 60 said they found a match their first time using the site. Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.10 level of significance, to reject the claim that the proportion, p , of all students who will find a match their first time using the site is 44% . erform a Z-test and find the p-value. Here is some information to help you with your Z-test. The value of the test statistic is given by −ppp−1pn . The p-value is two times the area under the curve to the left of the value of the test statistic. Standard Normal Distribution Step 1:…
The numbers of successes and the sample sizes for independent simple random samples from two populations are provided for a right-tailed test. Use a 90% confidence interval. Complete parts (a) through (d). X1 = 25, n, = 30, x2 = 17, n, = 70, a = 0.05 Click here to view a table of areas under the standard normal curve for negative values of z. Click here to view a table of areas under the standard normal curve for positive values of z. a. Determine the sample proportions. Determine the sample proportion p1. p = (Round to three decimal places as needed.) Determine the sample proportion p2. P2 = (Round to three decimal places as needed.) Determine the pooled sample proportion p,. (Round to three decimal places as needed.) b. Decide whether using the two-proportions z-procedures is appropriate. Check that the assumptions are satisfied. Select all that apply. A. The assumptions are satisfied, so using the procedures is appropriate. B. Since x, is less than 5, using the procedures is not…

A. reject the alternative hypothesis B. make a type I error C. accept the alternative hypothesis D. reject the null hypothesis E. accept the null hypothesis F. fail to reject the alternative hypothesis G. fail to reject the null hypothesis H. make a type II error
How do you write a null hypothesis and an alternative hypothesis in words? This is the question: The survey question: On the average day, about how many hours do you personally watch television? Suppose that your reading of professional research on the topic leads to the hypothesis that, on average, adults in the US watch three hours of TV each day. I planned to use a two-sided alternative hypothesis. In symbol, my null hypothesis would be H0 : equal 3 and my alternative hypothesis would be Ha not equal 3
Food inspectors inspect samples of food products to see if they are safe. This can be thought of as a hypothesis test with the following hypotheses. H0: the food is safe Ha: the food is not safe The following is an example of what type of error? The sample suggests that the food is safe, but it actually is not safe. Choose one below a. type I b. type II c. not an error
A credit card company claims that the mean credit card debt for individuals is greater than $5,100. You want to test this claim. You find that a random sample of 32 cardholders has a mean credit card balance of $5,242 and a standard deviation of $575. At a = 0.01, can you support the claim? Complete parts (a) through (d) below. Assume the population is normally distributed. (a) Write the claim mathematically and identify Ho and H2. Which of the following correctly states H, and H,? O A. Ho: µ> $5,100 Ha: us $5,100 В. Но: и- $5,100 Hai µ > $5,100 С. Но: 3 $5,100 Ha: u# $5,100 O D. Ho: µ2 $5,100 Ha:u $5,100 Ha: us $5,100 Ο F H0: μS $5,1 00 Ha: µ > $5,100 (b) Find the critical value and identify the rejection region. What is the critical value, to? to = 0 (Use a comma to separate answers as needed. Round to three decimal places as needed.) Determine the rejection region. Select the correct choice below and fill in the ansswer box within your choice. (Round to three decimal places as…
