The average American gets a haircut every 44 days. We want to know if the average is larger for college students. The data below shows the results of a survey of 12 college students asking them how many days elapse between haircuts. Assume that the distribution of the population is normal. 44, 45, 31, 42, 39, 46, 49, 50, 41, 42, 36, 36 The null and alternative hypotheses would be: Ho: ?V Select an answer Ha: ? Select an answer V
We want to estimate the mean of a certain population, so we will collect a sample. Which should be true if we use a large sample rather than a small one?I. The distribution of our sample data will be approximately normal.II. The sampling distribution of the sample means will be approximately normal.III. The variability of the sample means will be smaller. only I I, II, and III only III only II II and III
What value is estimated with a confidence interval using the t statistic? a. The value for an unknown sample mean b. The value for an unknown population mean c. The difference between two standard deviations d. The difference between two sample means
Determine whether the statement below makes sense or does not make sense. Explain clearly. Based on our sample, the 95% confidence interval for the mean amount of television watched by adults in a nation is 2.9 to 4.3 hours per day. Therefore, there is 95% chance that the mean for all adults in the nation will fall somewhere in this range and a 5% chance that it will not. C Choose the correct answer below. O A. The statement makes sense. There is 5% probability that the confidence interval limits do not contain the true value of the sample mean, so the probability it does not contain the true value of the population mean is also 5%. O B. The statement does not make sense. The population mean is a fixed constant that either falls within the confidence interval or it does not. There is no probability associated with this. O C. The statement does not make sense. The probability the population mean is greater than the upper limit is 5% and the probability it is less than the lower limit is…

K A R Explain how finding a confidence interval for a population variance is different from finding a confidence interval for a population mean or proportion. Choose the correct answer below. OA. Unlike a confidence interval for a population variance, a confidence interval for a population mean or proportion does not have a margin or error. The left and right endpoints must be calculated separately. OB.

The level of dissolved oxygen in a river is an important indicator of the water’s ability to support aquatic life. A research project is started to determine if the oxygen levels in the river have changed. It is known from a study done 10 years prior, that the mean oxygen levels in milligrams per liter for the river was 4.3. a- Write appropriate hypotheses for this test b- You collect water samples at 15 randomly chosen locations along the river and measure the dissolved oxygen. Here are your results in milligrams per liter: 4.53 5.5 4.01 5.04 4.83 4.66 3.29 4.4 2.87 5.23 5.42 5.73 4.13 6.38 5.55 Construct and interpret a 95% confidence interval for the mean dissolved oxygen level for this stream. c- Using the sample from part b, conduct a significance test of these results using a 5% significance level. Give complete results of the test including a p-value and an interpretation of the test results that someone not in this class could understand
