- At what age do babies learn to crawl? Does it take longer to learn in the winter when babies are often bundled in clothes that restrict their movement? Data were collected from parents who brought their babies into the University of Denver Infant Study Center to participate in one of a number of experiments between 1988 and 1991. Parents reported the birth month and the age at which their child was first able to creep or crawl a distance of four feet within one minute. The resulting data were grouped by month of birth. The data are for January, May, and September AverageBirth month crawling age SD nJanuary 29.84 7.08 32May 28.58 8.07 27September 33.83 6.93 38 Crawling age is given in weeks. Assume the data come from three independent simple random samples, one from each of the three populations (babies born in a particular month) and that the populations of crawling ages have normal…It has been noted that the amount of time people spend shopping in supermarkets has decreased due to the global pandemic. Based on this realization, the manager of Power Supermarket decided to collect data for the length of time people spend in his supermarket during a one week period. He is aiming to use the data to help him decide if the supermarket should be converted to a virtual supermarket/a delivery based one. Before the pandemic Time Frequency 1-5 50 6-10 25 11-15 22 16-20 80 20-25 60 25-30 45 30-35 35 After the pandemic Time Frequency 1-5 30 6-10 65 11-15 45 16-20 50 20-25 35 25-30 40 20-35 35 Use the information above to construct two frequency polygons. Do you think that Power Supermarket should close their doors? Explain your answer. *Assume that a person who spends more time in a supermarket buys a lot of goods and a person who spends a short time in a supermarket,…Is the magnitude of an earthquake related to the depth below the surface at which the quake occurs? Let x be the magnitude of an earthquake (on the Richter scale), and let y be the depth (in kilometers) of the quake below the surface at the epicenter. x 2.8 3.9 3.3 4.5 2.6 3.2 3.4y 4.7 9.6 11.2 10.0 7.9 3.9 5.5(a) Make a scatter diagram of the data.Flash Player version 10 or higher is required for this question. You can get Flash Player free from Adobe's website. Then visualize the line you think best fits the data. (b) Use a calculator to verify that Σx = 23.7, Σx2 = 82.75, Σy = 52.8, Σy2 = 447.56 and Σxy = 184.28. Compute r. (Round to 3 decimal places.) As x increases, does the value of r imply that y should tend to increase or decrease? Explain your answer.Given our value of r, we can not draw any conclusions for the behavior of y as x increases.Given our value of r, y should tend to remain constant as x increases. Given our value of r, y should tend to decrease as x increases.Given…

Select the two correct answers. The median upload speed during peak hours is 5.905 megabits per second, which is less than the median upload speed during off-peak hours, 7.005 megabits per second. The upload speeds during peak hours are slower on average compared to off-peak times. The median upload speed during peak hours is 6.37 megabits per second, which is greater than the median upload speed during…Which of the required conditions for cause and effect is easiest to establish in nonexperimental research? A. lack of alternative explanation B. relationship C. All three conditions are equally easy to establish. D. proper time orderIn a study, the effects of the mane of a male lion as a signal of quality to mates and rivals was explored. Four life-sized dummies of male lions provided a tool for testing female response to the unfamiliar lions whose manes varied by length (long or short) and color (blonde or dark). The female lions were observed to see whether they approached each of the four life-sized dummies. Complete parts (a) through (e) below. a. Identify the experimental units. Choose the correct answer below. The female lions The male dummies The mane colors The mane lengths Part 2 b. Identify the response variable. Choose the correct answer below. A. Whether or not (yes or no) the mane length affected how the female lions reacted to a male dummy. B. Whether or not (yes or no) the female lions approached the same dummies. C. Whether or not (yes or no) the female lions approached a male dummy. D. Whether or not…

Due to covid-19 pandemic, wearing a facemask of a person is required for their safety. Since there are limited stocks available, she decided to start another business by making a facemask. She started selling facemask from day 1 to day 10. The data she collected is shown in the table belowA researcher with the Department of Education followed a cohort of students who graduated from high school in a certain year, monitoring the progress the students made toward completing a bachelor's degree. One aspect of his research was to determine whether students who first attended community college took longer to attain a bachelor's degree than those who immediately attended and remained at a 4-year institution. The data in the table attached below summarize the results of his study. Complete parts a) through e) below.

Woodpeckers are valuable forest asset, both because they provide nest and roost holes for other animals and birds and because they prey on many forest insect pests. The article “Artificial Trees as a Cavity Substrate for Woodpeckers” reported on a study of how woodpeckers behaved when provided with polystyrene cylinders as an alternative roost and nest cavity substrate. We give selected value of x = ambient temperature (C) and y = cavity depth (cm); these values were read from the article: (VIEW IMAGE) Construct a 95% Confidence Interval for the slope of the linear relationship between temperature and depth.
