Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.

Question

He randomly selected 25 adults who do
exercise of one or more hours per day, and
registered the number of hours they sleep.
The sample data gave the investigator the

A soda company sells one of its soft drinks in 12 ounce cans. In order to ensure that every can has at least 12 ounces in it, the machines in the factory are set to fill each can with an average of 12.1 ounces of soda. Every week, a quality-control technician tests 10 cans to make sure that the average amount of soda in the cans is still 12.1 ounces. If the conclusion of the test is that the number of ounces of soda in the cans is different from 12.1, the technician will declare that the process is out of control, and the machine will be stopped and calibrated. From previous tests, the technician found that the standard deviation of the number of ounces of soda in the cans is approximately 0.01. The number of ounces of soda in the 10 cans that were tested this week is given below. Assume that the standard deviation from the technician's previous tests is the population standard deviation. Use a TI-83, TI-83 Plus, or TI-84 calculator to test whether filling process is out of control and…

A researcher hypothesizes that people are more likely to be tired after a week of using the computer for 10 hours daily, without wearing blue-light glasses. The researcher randomly assigned 36 participants to one of two groups (Group 1 = without blue-light glasses vs Group 2 = with blue-light glasses). Then, the researcher monitored how many times each participant yawned per hour. How do we represent the alternative hypothesis for this study? Please write this out in words, or express it mathematically.
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
According to the National Health and Nutrition Examination Survey (NHANES) sponsored by the U.S. government, a random sample of 712 males between 20 and 29 years of age and a random sample of 1,001 males over the age of 75 were chosen and the weight of each of the males were recorded (in kg). Do the data provide evidence that the younger male population weighs more (on average) than the older male population? Use “Y” for ages 20-29 and “S” for ages 75+. It was found that x̅Y=83.4, sY=18.7, x̅S=78.5, and sS=19.0. a) Is the normality condition met for this test? (see picture) No, since the histograms show skewness and outliers . Yes, since both sample sizes are larger than 30. No, since both sample sizes, nY and nS, are less than 30. Yes, since it was stated that the two populations are normally distributed. b)What are the correct degrees of freedom for this test? Group of answer choices 999 1000 1712 1711 711
