Hi, We are supposed to answer one question at a time. Since you have not mentioned which question to answer. I am answering the first one. Please repost the remaining questions that you would like to be answered.
1.
Following assumptions have been taken for the population. These values will be used in the further calculations.
I claim that more than 50% of the people follow have heavy working lifestyle (p > 0.5)
I claim that people do exercise 2 days a week on an average.
I claim that the average weight of the people is atleast 160 pounds.
my questions is q1. what type of lifestyle do you have in terms of physical activity?...
ONLY DO NUMBER 3 For this project you will test claims and conjectures using hypothesis testing. For each hypothesis test, report the following: The null hypothesis, H0 The alternative hypothesis, H1 The test statistic rounded to the nearest hundredth (use T Stats or Proportion Stats in StatCrunch to find test statistics) The P-value for the test (use T Stats or Proportion Stats in StatCrunch to find P-values) The formal decision (Reject H0 or Fail to reject H0, remember that reject...

I need help determining the decision for null hypothesis. For 1&2, set the type one error to 1% for 3-5, set the type one error to 5% Go to Statcrunch shared data sets and use the file Nutritional Data for Fast Food 2017. Set the type one error equal to 1% Complete the following: 1) Use STAT - proportions stats - one sample w data to test the hypothesis that the proportion of "burgers" made by Wendy's restaurants is less...
While you do not have to do so, it is recommended that you draw the pictures before solving the problems. 1. To FOUR DECIMAL PLACES: Determine the area under the standard normal curve that lies a. to the left of Z = –1.31 b. to the right of Z = –2.47 c. between Z = –2.47 and Z = –1.31 d. between Z = 1.31 and Z = 2.47 2. Find the z-scores that separate the middle 84% of the...
sorry for the mutiples.. wanna ask my questions before my sub ends.. per day. A 5) A simple random sample of size n=1320 is obtained from a population whose size is N=1,400,000 and whose population proportion with a specified characteristic is p=0.46. Describe the sampling distribution of 1) The mean number of violent crimes committed in a day is 2.2 crimes per day with a standard deviation of 6 crimes per day. A random sample of 100 days was observed,...
Question 1 Question Type 1 The following data sets each contain 3 random observations of two variables. For each data set, answer the following questions: Question (a) The data below is a random sample of 3 observations drawn from the United States population. Use the data to answer the following questions i. Find 95% confidence intervals of the population mean of experience and wage ii. Estimate pe,w, the correlation between the variables experience and wage. iii. Find Bı and Po,...
Can someone explain on how to do 2 and 3 please thank you. would reject the claim. an effective way to treat Covid-19. 2. You wish to estimate, with 95% confidence, the mean time it takes to pet all of the cats at the animal shelter. You observe 13 random people and find that the average amount of time it took to pet the cats was 23 minutes with a standard deviation of 24 minutes. Assume the population is normally...
3. Suppose you and your class mate have to do a group assignment. Both of you can decide to work or shirk. If you both work, then both will get a good mark but both incur the cost of working. If one person works, you get a bad mark but the person who shirked will not have to put in the effort. If both shirk then the students fail. The following table represents the individuals’ utilities (as always the first...
Project #2: Chapter 3 Collect information on any quantitative variable for 30 members as you did for Mini-Project 1-1. Choose a different project this time, however Once you have collected the data, answer the following questions: a. List the data b. What is the target population for the sample you used? Be specific. c. Is your sample a random sample from this target population? Explain your answer. d. Do you think your sample is representative of this population? Explain why...
Option 1 or 2 Option 1: Think about a population mean that you may be interested in and propose a confidence interval problem for this parameter. Your data values should be approximately normal. For example, you may want to estimate the population mean number of times that adults go out for dinner each week. Your data could be that you spoke with seven people you know and found that they went out 2, 0, 1, 5, 0, 2, and 3...
