The claim is that smokers have a mean cotinine level greater than the level of 2.84 ng/ mL found fornonsmokers. (Cotinine is used as a biomarker for exposure to nicotine.) The sample size is n = 918 and thetest statistic is t = 56.582. Use technology to find the P-value. Based on the result, what is thefinal conclusion? Use a significance level of 0.05.Begin by using the original claim to identify the null hypothesis and the alternative hypothesis for this test.The null hypothesis (denoted by Ho) is a statement that the value of a population parameter (suchas proportion, mean, or standard deviation) is equal to some claimed value. The alternativehypothesis (denoted by H, or Ha or Ha) is a statement that the parameter has a value that somehow differsfrom the null hypothesis.

Given that Sample size n =918 Population mean =2.84 Test statistic t =56.582

An industrial company claims that the mean pH level of the water in a nearby river is 6.8. You randomly select 19 water samples and measure their pH. The mean and standard deviation are 6.7 and 0.24, respectively. Is there enough evidence to reject the company’s claim at a significance level of 0.05? Assume the population is normally distributed.

Systolic blood pressure levels above 120 mm Hg are considered to be high. For the 100 systolic blood pressure levels listed in the accompanying data set, the mean is 125.70000 mm Hg and the standard deviation is 15.86146 mm Hg. Assume that a simple random sample has been selected. Use a 0.01 significance level to test the claim that the sample is from a population with a mean greater than 120 mm Hg. Click the icon to view the data set of systolic blood pressure levels.
Many cheeses are produced in the shape of a wheel. Because of the differences in consistency between these different types of cheese, the amount of cheese, measured by weight, varies from wheel to wheel. Heidi Cembert wishes to determine whether there is a significant difference, at the 10% level, between the weight per wheel of Gouda and Brie cheese. She randomly samples 18 wheels of Gouda and finds the mean is 1.3 lb with a standard deviation of 0.3 lb; she then randomly samples 10 wheels of Brie and finds a mean of 0.95 lb and a standard deviation of 0.21 lb. What is the df and p-value for Heidi's hypothesis of equality? Assume normality. (Give your answer correct to four decimal places.)
Big babies: The National Health Statistics Reports described a study in which a sample of 335 one-year-old baby boys were weighed. Their mean weight was 25.2 pounds with standard deviation 5,3 pounds. A pediatrician claims that the mean weight of one-year-old boys differs from 25 pounds. Do the data provide convincing evidence that the pediatrician's claim is true? Use the a= 0.01 level of significance and the P-value method with the TI-84 Plus calculator. Answer the following three.
280 men are found to have an average pulse rate of 73 (beats per minute) with standard deviation 5.4, and 240 women are found to have an average pulse rate of 72 (beats per minute) with standard deviation 7.7. A researcher is interested in whether, on average, men have higher pulse rates than women. What is the most appropriate test for the researcher to use? A. chi-square test B. z-test for the difference between two proportions C. paired sample t-test D. two sample t-test
An automobile manufacturer claims that their van has a 50.750.7 miles/gallon (MPG) rating. An independent testing firm has been contracted to test the MPG for this van. After testing 2323 vans they found a mean MPG of 50.950.9 with a standard deviation of 2.02.0. Is there sufficient evidence at the 0.10.1 level that the vans outperform the manufacturer's MPG rating? Assume the population distribution is approximately normal. Step 1 of 5 : State the null and alternative hypotheses.
