A researcher is 95% confident that the interval from 19.7 posts to 27.3 posts captures mu = the true mean amount of posts high school students make daily on social media. there evidence that the true mean number of posts high school students make is less than 27 No. There is not evidence for the population mean to be less than 27, because 27 is within the 95% confidence Interval No. There is not evidence for the population mean to be less than 27, because there are values greater than 27 within the 95% confidence interval Yesthere is evidence for the population mean to be less than 27because 27 is within the 95% confidence interval Yes, there is evidence for the population mean to be less than 27, because 27 is closer to the upper bound of the 95\% confidence interval than the lower bound .

Say we have a population parameter μ, and the 95% confidence interval for it is (-3, 10). - What can you say to someone who claims that u 11 ? You would accept their claim. You would reject their claim.
This is the result of Chi Square test between 2 variables: gender and length of service. If the Null Hypothesis is stated as "There is no significant association between gender and length of service", then table above will clearly allow us to conclude that "there is no significant association between gender and length of service".

Suppose you have a model Y = B₁ + B₂X₂ + uż that satisfies all CNLRM assumption with 8 observations, and the o2 = 36. What is the 95% confidence interval of o²? (17.17, 98.19) (18.63, 132.46) (17.75, 145.56) (14.95, 174.62) Do not have enough information
A certain counselor wants to compare mean IQ scores for two different social groups. A random sample of 14 IQ scores from group 1 showed a mean of 91 and a standard deviation of 17, while an independently chosen random sample of 13 IQ scores from group 2 showed a mean of 80 and a standard deviation of 16. Assuming that the populations of IQ scores are normally distributed for each of the groups and that the variances of these populations are equal, construct a 95% confidence interval for the difference u, -u, between the mean u, of IQ scores of group 1 and the mean u, of IQ scores of group 2. Then find the lower limit and upper limit of the 95% confidence interval. Carry your intermediate computations to at least three decimal places. Round your responses to at least two decimal places. (If necessary, consult a list of formulas.) Lower limit:| Upper limit:
A study conducted by the research institute of America has concluded that the mean number of hours a person spends in their car during a typical week in 1999 I5 hours. Given that times have changed in the past 20 years in terms of employment rates and public transit, it is reasonable to believe people spend more or less time in their car every week. Because we can see it going either way, we want to test the null hypothesis that the people spend 15 hours in their car against our alternative hypothesis that people spend a different amount of time in the car in 2019 compared to 1999. To test this hypothesis, assume we distributed a survey to 100 randomly selected adults in San Antonio as asked them about their driving background. We found the following information: Sample Statistics: I time spent in a car = 18.3 hours (SD = 11.7) Use this information to complete ALL 5 steps of hypothesis testing. You should
You calculate a 95% confidence interval for the true length in inches of "foot- long" sandwiches to be (11.15, 12.05). If a consumer group claims that these "foot-long" sandwiches are not actually an average of 1 foot long, does your interval support their claim (at alpha=.05)? No, it does not support their claim. Yes, it supports their claim. Cannot determine Sometimes yes and sometimes no
A certain counselor wants to compare mean IQ scores for two different social groups. A random sample of 11 IQ scores from group 1 showed a mean of 120 and a standard deviation of 16, while an independently chosen random sample of 10 IQ scores from group 2 showed a mean of 113 and a standard deviation of 14. Assuming that the populations of IQ scores are normally distributed for each of the groups and that the variances of these populations are equal, construct a 90% confidence interval for the difference u,-, between the mean u, of IQ scores of group 1 and the mean u, of IQ scores of group 2. Then find the lower limit and upper limit of the 90% confidence interval. Carry your intermediate computations to at least three decimal places. Round your responses to at least two decimal places.

A random sample of 12 IQ scores from group 1 showed a mean of 95 and a standard deviation of 16, while an independently chosen random sample of 16 IQ scores from group 2 showed a mean of 101 and a standard deviation of 13. Assuming that the populations of IQ scores are normally distributed for each of the groups and that the variances of these populations are equal, construct a 90% confidence interval for the difference u, - µ, between the mean µ¡ of IQ scores of group 1 and the mean u, of IQ scores of group 2.
