Question

Someone took 6 samples, they found an average of 8.5 # /1 with a standard deviation of 1.6 #/1
a) Assume normal distribution and standard deviation is representative of the population value,
calculate a 90% two sided confidence interval for the mean concentration
b) Calculate a one sided upper limit on the average, consider the small sample size and use t-

The annual rainfall in a certain region is modeled using the normal distribution shown below. The mean of the distribution is 41.8 cm and the standard deviation is 5.3 cm. In the figure, V is a number along the axis and is under the highest part of the curve. And, Uand W are numbers along the axis that are each the same distance away from Use the empirical rule to choose the best value for the percentage of the area under the curve that is shaded, and find the values of U, V, and W. Percentage of total area shaded: (Choose one) 30 35 40 45 50 55 60 ( cm)
The mg of nicotine in menthol cigarettes is normally distributed and a sample of 25 menthol cigarettes had a standard deviation of 0.24 mg of nicotine. We will be constructing a 90% confidence interval containing the population variance. The left hand critical value is . Round to 3 decimal places. The right hand critical value is .

The average American consumes 86 liters of alcohol per year. Does the average college student consume more alcohol per year? A researcher surveyed 15 randomly selected college students and found that they averaged 94.2 liters of alcohol consumed per year with a standard deviation of 24 liters. What can be concluded at the α = 0.05 level of significance? For this study, we should use Select an answer z-test for a population proportion t-test for a population mean The null and alternative hypotheses would be: H0:H0: ? p μ Select an answer = < ≠ > H1:H1: ? p μ Select an answer ≠ = > < The test statistic? z t = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is ? > ≤ αα Based on this, we should -------- the null hypothesis. Thus, the final conclusion is that ... The data suggest the population mean is not significantly more than 86 at αα = 0.05, so there is statistically…
