Q03 A doctor claims that 17 year olds have an average body temperature that is higher than the commonly accepted average human temperature of 98.6 degrees. The two hypothesis used are H0: μ = 98.6 and Ha: μ > 98.6. A 0.02 level of significance was used. What is the conclusion if you Fail To Reject H0.
Select one: a. The average temperature of 17 year olds is 98.6 degrees. b. At the 0.02 level of significance data does not support that the average temperature of 17 year olds is greater than 98.6 degrees. c. At the 0.02 level of significance data supports that the average temperature of 17 year olds is greater than 98.6 degrees. d. There is a 98% chance that the average temperature of 17 year olds is 98.6 degrees.

Nancy, a golfer, claims that her average driving distance is 253 yards. During a practice session, Nancy has a sample driving distance mean of 229.6 yards based on 18 drives. At the 2% significance level, does the data provide sufficient evidence to conclude that Nancy's mean driving distance is less than 253 yards? Accept or reject the hypothesis given the sample data below. H0:μ=253 yards; Ha:μ<253 yards α=0.02 (significance level) z0=−0.75 p=0.2266 Select the correct answer below: Do not reject...

The average temperature in St. Louis in November of 2018 was 38.8oF38.8oF . The unusually cold weather in St. Louis and other places around the country prompted President Trump to tweet at the time that this was proof that global warming cannot be real. Let’s put that claim to a statistical test: According to the National Oceanic and Atmospheric Administration (NOAA, retrieved from www.weather.gov), the average daily temperature in St. Louis in November (starting in 1838) is 45.05oF use this...
What is normal, when it comes to people's body temperatures? A random sample of 130 human body temperatures had a mean of 98.15° and a standard deviation of 0.74°. Does the data indicate that the average body temperature for healthy humans deviates from 9
Test using the p-value approach with ? = 0.05.State the null and alternative hypothesis.H0: ? < 98.6 versus Ha: ? > 98.6H0: ? = 98.6 versus Ha: ? > 98.6 H0: ? = 98.6 versus Ha: ? < 98.6H0: ? = 98.6 versus Ha: ? ≠ 98.6H0: ? ≠ 98.6 versus Ha: ? = 98.6Find the test statistic and the p-value.

It has long been reported that human body temperature follows a normal distribution with a mean of 98.6 degrees Fahrenheit. There is some debate in the medical field, however, about this long-held standard of human body temperature. Specifically, some medical researchers believe that the average human body temperature is actually greater than 98.6 degrees Fahrenheit. To test their theory, these researchers measured the body temperature of a random sample of 180 healthy individuals. The researchers then recorded the mean and...

The average number of accidents at controlled intersections per year is 5.6. Is this average more for intersections with cameras installed? The 47 randomly observed intersections with cameras installed had an average of 6 accidents per year and the standard deviation was 1.25. What can be concluded at the αα = 0.05 level of significance? For this study, we should use Select an answer? t-test for a population mean or z-test for a population proportion The null and alternative hypotheses...

The Nero Match Company sells matchboxes that are supposed to
have an average of 40 matches per box, with σ = 8. A
random sample of 94 matchboxes shows the average number of matches
per box to be 42.2. Using a 1% level of significance, can you say
that the average number of matches per box is more than 40?

Sometimes when you are sick, your forehead feels really warm. You might have fever. How can you find out whether you do? By taking your temperature, of course. But what temperature should the thermometer show if your're healthy? Is this temperature the same for everyone? Several years ago, researchers conducted a study to determine whether the "accepted" value for normal body temperature, 98.6°F, is accurate. They used an oral thermometer to measure the temperatures of a random sample of healthy...

The average annual miles driven per vehicle in the United States is 11.1 thousand miles, with σ ≈ 600 miles. Suppose that a random sample of 41 vehicles owned by residents of Chicago showed that the average mileage driven last year was 10.9 thousand miles. Does this indicate that the average miles driven per vehicle in Chicago is different from (higher or lower than) the national average? Use a 0.05 level of significance.
