A Troublesome Snowball One winter afternoon, unbeknownst to his mom, a child bring a snowball into the house, lays it on the floor, and then goes to watch T.V. Let W=W(t) be the volume of dirty water that has soaked into the carpet t minutes after the snowball was deposited on the floor. Explain in practical terms what the limiting value of W represents, and tell what has happened physically when this limiting value is reached.
Workers in the office like to drink coffee during work. A doctor is concerned about this situation since the too much coffee consumption may result to long-term health problems. However, studies suggests that there is no risk in drinking three cups of coffee per day, which is about 250 mg of caffeine. The doctor wants to know if the amount of caffeine consumed by the workers is within tolerable limits. He randomly selected 20 students and found that they consume an average of 270 mg of caffeine each day with a standard deviation of 48 mg. Assume that the daily amount of caffeine consumed by students follow the normal distribution.1. Which of the following sets of hypotheses should be used in this study? A. Ho: μ = 250 vs. Ha: μ > 250 B. Ho: μ ≤ 250 vs. Ha: μ > 250 C. Ho: μ = 270 vs. Ha: μ > 270 D. Ho: μ = 270 vs. Ha: μ ≠ 270 2. Which of the following is(are) TRUE? I. The appropriate test procedure to answer the objective of the study is a…
Victims of Violence A random survey of 75 women who were victims of violence found that 22 were attacked by relatives. A random survey of 53 men found that 14 were attacked by relatives. At a=0.05, can it be shown that the percentage of women who were attacked by relatives is less than the percentage of men who were attacked by relatives? Use p1 for the proportion of women who were attacked by relatives. Use the P-value method with tables. Part 2. State the hypotheses and identify the claim with the correct hypothesis. Part 3. Compute the test value. Always round score values to two decimal places. Part 4. Find the -value. Round the answer to four decimal places. Part 5. Reject or not to reject the null hypothesis.
You are conducting a study to see if the proportion of women over 40 who regularly have mammograms is significantly more than 82%. With H1 : p >> 82% you obtain a test statistic of z=1.203z=1.203. Find the p-value accurate to 4 decimal places.p-value =
You are conducting a study to see if the proportion of women over 40 who regularly have mammograms is significantly more than 82%. With H1 : p >> 82% you obtain a test statistic of z=1.203z=1.203. Find the p-value accurate to 4 decimal places.
Victims of Violence A random survey of 86 women who were victims of violence found that 20 were attacked by relatives. A random survey of 54 men found that 6 were attacked by relatives. At α=0.10, can it be shown that the percentage of women who were attacked by relatives is different from the percentage of men who were attacked by relatives? Use p1 for the proportion of women who were attacked by relatives. Use the P-value method with tables. State the hypotheses and identify the claim with the correct hypothesis. H0: claim/do not claim? H1: claim/do not claim? This hypothesis test is one tailed/two tailed? Compute the test value. Round all intermediate steps to four decimal places and always round z score values to tow decimal places. Z= Compute the P-value. Round the answer to four decimal places. P -value = Make the decision. Reject/do not reject the null hypothesis. Summarize the results. There is/ is not enough evidence to support the claim t
You are conducting a study to see if the proportion of voters who prefer Candidate A is significantly more than 50%. With H1 : p > 50% you obtain a test statistic of z = 1.427 . Find the p-value accurate to 4 decimal places.
A test of the claim that the proportion of students taking more than 9 units is more than 42% produces the test statistic z = 1.76. Find the P-value.
A new process for producing silicon wafers for integrated circuits is supposed to reduce the proportion of defectives to 10%. A sample of 250 wafers will be tested. Let X represent the number of defectives in the sample. Let p represent the population proportion of defectives produced by the new process. A test will be made of H0 : p ≥ 0.10 versus H1 : p < 0.10. Assume the true value of p is actually 0.06. a) It is decided to reject H0 if X ≤ 18. Find the level of this test. b) It is decided to reject H0 if X ≤ 18. Find the power of this test. c) Should you use the same standard deviation for X to compute both the power and the level? Explain. d) How many wafers should be sampled so that the power is 0.90 if the test is made at the 5% level?
p = proportion of students who abandon their studies due to lack of economic resources A sociologist assures that in his country more than 40% of the students who abandon their studies lack economic resources. He takes a sample of 70 student dropouts and finds that 35 of them lack financial resources. Can the sociologist, with a level of significance α = 0.05, consider that, among the dropout students, those who lack economic resources are a percentage greater than 40%? He calculates with 4 decimals Choose: 1. the correct conclusion2. the correct interpretation Select one: a) 1. H0 is not rejected2. There is not enough evidence to consider, with a confidence of 95%, that the percentage of those who lack economic resources among the students who abandon their studies is greater than 40%. b) 1. H0 is rejected2. There is not enough evidence to consider, with a confidence of 95%, that the percentage of those who lack economic resources among the students who abandon their studies is…
Water Consumption The Old Farmer’s Almanac stated that the average consumption of water per person per day was 123 gallons. To test the hypothesis that this figure may no longer be true, a researcher randomly selected 16 people and found that they used on average 119 gallons per day and s = 5.3. At α = 0.05, is there enough evidence to say that the Old Farmer’s Almanac figure might no longer be correct? Use the Critical Value method.
