A one-sample t-test for testing Ho: = - 1.5 against Ho: H # - 1.5 resulted in a p-value of 0.072. Basedon the same sample, would the 90% confidence interval and the 95% confidence interval for u containthe value -1.5?Only the 90% confidence interval would contain -1.5Only the 95% confidence interval would contain -1.5Neither the 90% confidence interval nor the 95% confidence interval would contain -1.51.Both the 90% confidence interval and the 95% confidence interval would contain -1.5

From the provided information, Null hypothesis: H0: µ = -1.5 Alternative hypothesis: H1: µ ≠ -1.5…

Suppose we are testing brake light reaction times for a new brake light design. The current design (we will call it the old design) is known to have an average reaction time of 0.8 seconds. A random sample of 50 drivers are tested on the new design, and the 50 drivers have an average reaction time of 0.76 seconds, with a 95% confidence interval of (0.66, 0.86) seconds. Write a few sentences to explain how we should interpret this data. Explain what the null hypothesis is here, whether we rejected the null, or failed to reject, and also what the implications are.
A telephone poll of 841 adult Americans was reported in an issue of Time Magazine. One of the questions asked was, "What is the main problem facing the country?" Forty percent answered, "crime." Construct a 88% confidence interval for the population proportion of Americans who feel that crime is the main problem.p'=α2=zα2=Margin of Error: EWe are 88% confident that the proportion of Americans who feel that crime is the main problem is between___and ____.
Modern laser equipment has been used to measure the distance between two points. Each measurement value can be seen as an observation of a normally distributed variable X, with the real distance UX as expected value and standard deviation OX=2.87. After collecting n=18 independent measurements have calculated that the average value is X = 3016 A student finds the upper and lower bounds of a 90% confidence interval for the real distance UX. Upper = 3017.1 Lower = 3014.9 How many observations do we need to get the length of the confidence interval down to 1.0 meters?
Let's examine the relationship between CI's and hypothesis tests: (a) You calculate a 90% confidence interval for μ and come up with (-26, 10). If you test H0: μ = -7 and use α = .10, will you reject H0? Why or why not? (b) Now you calculate a 95% CI for μ and come up with (-5, -1). If you test H0: μ = 0 and use α = .10, will you reject H0? Why or why not? (c) Finally, you calculate a 95% CI for for μ and come up with (-24, -8). If you test H0: μ = - 13 and use α = .01, will you reject H0? Why or why not?

The mean IQ for the entire population in any age group is known to be 100 with a standard deviation of 15. Suppose the IQ scores of 72 12th graders in Columbus are measured and the sample mean is found to be 103.4 and the sample standard deviation is 20.2. Do the scores provide good evidence that the mean IQ of this population is not 100? State the null (H0) and alternative (Ha) hypotheses. 2. What are the confidence intervals for this data? 3. What is the value of the test statistic? 4. What is the p-value for this data? 5. What is your decision about the null hypothesis?: Reject Fail to Reject 6.

The Woodcock-Johnson Cognitive Ability test indicates that the average score is 95. The same group of 12th grade students (n = 72) in Columbus are tested and the sample mean is 110.1 and the sample standard deviation is 15.2. Do the scores provide good evidence that the mean IQ of this population is greater than 95? State the null (H0) and alternative (Ha) hypotheses. What are the confidence intervals for this data? What is the value of the test statistic? What is the p-value for this data? What is your decision about the null hypothesis? summerize the conclusion in the context
