When peforming a hypothesis test a sample is gathered to test the claim being made. When the sample evidence differs from the claimed value, how can you determine if that difference is just to do randomness or due to there being a statistically significant difference between the sample evidence and claimed value?
Homework Answers
To determine if that the difference is just to do randomness we set level of significance which is set as to tolerable probability of randomness significancy. if the significancy is greater than level of significance than we say that there significant difference between the sample evidence and claimed value. here we use P_value to see the significance which is the probability of obtaining an effect atleast as extreme as the one in sample data by assuming the truth of the null hypothesis.

6. A claim is made that college students spend 75% of their time on either sleeping or socializing. You do not believe this claim, and you set out to conduct a hypothesis test with the following hypotheses: Ho: p = 0.75 vs. Ha: p ≠ 0.75. If you gather data from a sample and compute a test statistic equal to -0.6, what would the p-value be? 7. Return to Question 6. The fact that the test statistic is negative tells...

How do you know if a hypothesis test is testing the claim between 2 population proportions or 2 means? How is the test statistic for a claim about 2 population means, independent samples, standard deviations unknown, similar to the test statistic for 1 population mean, standard deviation unknown? If the difference between the 2 population means is not significant, which means the test statistic falls within the "usual" area of the distribution, what is the decision about the null hypothesis?...

Randomly selected statistics students participated in an experiment to test their ability to determine when 1 minute (or 60 seconds) has passed. 44 students yielded a sample mean of 58.3 seconds. Assume that = 9.5 seconds. a) Use a 0.05 significance level to test the claim that the population mean is equal to 60 seconds. Claim: ---Select--- < > = ≠ ≤ ≥ 60 Ho: ---Select--- < > = ≠ ≤ ≥ 60 H1: ---Select--- < > = ≠ ≤ ≥ 60 b) What...

Use a hypothesis test to test the given claim. A test of sobriety involves measuring the subject's motor skills. Twenty randomly selected sober subjects take the test and produce a mean score of 41.0 with a standard deviation of 3.4. At a significance level of 0.01, test the claim that the true mean score for all sober subjects is equal to 39.0. Group of answer choices a) There is not enough information to perform the test. b) Fail to reject...

A nutrition expert claims that the average American is overweight. To test his claim, a random sample of 20 Americans was selected, and the difference between each person's actual weight and idea weight was calculated. For this data, we have x¯=19.5 and s=29.8. Is there sufficient evidence to conclude that the expert's claim is true? Carry out a hypothesis test at a 4% significance level. Hint: Pay attention to the variable being measured: the difference between actual weight and ideal....

Identify the CONCLUSION of a hypothesis test of the following claim and sample data: Claim: “The proportion of symptom-free placebo subjects is less than the proportion of symptom-free subjects who received a new supplement.” A medical researcher wants to determine if a new supplement is effective at reducing the duration of the common cold. Healthy subjects are intentionally infected with a cold-causing virus, and then given either a placebo or the new supplement one day later. Of the 267 subjects...

Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Among 2031 passenger cars in a particular region, 227 had only rear license plates. Among 300 commercial trucks, 45 had only rear license plates. A reasonable hypothesis is that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars....
