Researchers were interested in the number of outdoor walksweek that people had taken during the COVID-19 lock down based on the neighborhood that they lived in. People were recruited from Midtown Toronto, Markham, and Maple. Researchers justified the differentneighborhoods based on congestion and outdoor spaces. The researchers wanted to see if there was a signficiant difference between the number of outdoor walks a week based on neighborhood. Here is the data that they collectedMidtown Toronto: 1 3 4 2 4Markam: 4 3 4 5Maple: 10 7 6 9 8Test the hypothesis at the 5% significance level (a = 0.05) using the 5-step hypothesis testing procedure (show ALL steps).

Researchers investigated two kinds of laugh tracks – one with posed laughter and one with spontaneous laughter. Recall that to create the posed laughter laugh track, the researchers asked people to laugh and recorded the results. The researchers also tested the same 40 jokes with a spontaneous laughing laugh track, which they created by having people watch funny videos and recording their laughter. The data can be found in the file LaughTypes in pictures. Put these data into the Matched Pairs applet to investigate whether the type of laughter makes a difference in the ratings of the jokes and also do parts (a) (b) and (c):

Researchers conducted a study to find out if there is a difference in the use of online-learning by different age groups. Randomly selected participants were divided into two age groups. In the 16 to 29-year-old group, 7% of the 628 surveyed use online-learning, while 11% of the 2,309 participants 30 years old and older use online learning. (Set 1 for 16-29 year old group; Set 2 for 30 years old and older). Find X2.
Burning fuels in power plants and motor vehicles emits carbon dioxide (CO2), which contributes to global warming. The CO2 emissions (metric tons per capita) for countries varies from 0.02 in Burundi to 44.02 in Qatar. Although the data set includes 214 countries, the CO2 emissions of 15 countries are not available on the World Bank database. The data set is too large to display but the data for the first five countries is given. Use the full data set with data on the 214 countries to answer the questions.

Suppose the doctors at a local office take a health survey of 100 adult female patients with similar weight who have had appointments in the last week. According to their medical file, the 100 participants all weigh between 140 – 149 lbs. One of the survey questions asks participants to list their current weight. The accompanying tables show the relative frequency of weights measured by the physician for the 100 participants and the relative frequency of weights recorded in the survey for the 100 participants. Note that some of the weights reported in the survey did not fall between 140 – 149 lbs.

The U.S. Census Bureau serves as the leading source of quantitative data about the na- tion's people and economy. The following crosstabulation shows the number of house- holds (1000s) and the household income by the highest level of education for the head of household (U.S. Census Bureau website, 2013). Only households in which the head has a high school diploma or more are included.
The council leaders of a small town would like to determine the average number of people living in each household. To accomplish this, they send a questionnaire to each residence listed in the town address records, asking the head of the household to record the number of people living in the dwelling. They follow this up with visits to those households that have not responded to the questionnaire until the data collection process is complete. Which of the following is the best description of the method for data collection used by the council leaders? (A) A convenience sample (B) A simple random sample (C) A stratified random sample (D) A cluster random sample (E) A census

15 wheelchair users were randomly assigned to three groups with 5 in each group. These participants navigated in virtual-reality settings. Group 1 participants were in the virtual-reality setting (a building) as wheelchair users. Group 2 participants were in the virtual-reality setting in a wheelchair pushed by a walking person. Group 3 participants walked without aid in the virtual-reality setting. Joan measured the time each participant needed to complete the navigation of the virtual-reality setting. What is the independent variable(s)?
The National Safety Board wants to determine the effect of seat belt use on saving lives. One study showed data on children under the age of 5 who were involved in car accidents in which at least one fatality occurred.
