Please note, do not conduct inferencein this problem; just answer each question.A researcher wanted to use a random sample of 20 Spotify Songs to estimate the averageDuration (in minutes) and average Tempo (in bpm) for the population of all songs on Spotify.The researcher does not have any additional information about the population of all SpotifySongs. The data set is called Song Sample1.a) Based on the above scenario, which method of statistical inference do you believe theresearcher will consider to complete this estimation? Answer this question in onesentence and provide a reason for your choice.b) If we attempt to conduct statistical inference using the collected sample, what are the twoparameters of interest to the researcher? Use the correct symbols and describe theparameters in context in one sentence each.c) Check the following conditions necessary to consider conducting inference using theory-based methods and the t-distribution. There are three to consider: (1) Was a randomsample collected; (2) Is the population where the sample comes from normal; and (3) Isthe sample size greater than or equal to 30? Check each of these conditions in onesentence.d) For the Duration variable, construct a frequency histogram in Rguroo. Remember toproperly title and label the graph. Copy and paste this graph into your document.e) Describe the shape of the Duration histogram in one sentence.f)For the Duration variable, construct one horizontal boxplots in Rguroo. Remember toproperly title and label the graph. Copy and paste this graph into your document.g) Does the Duration boxplot show any outliers? Answer this question in one sentence andidentify any outliers if they are present.h) For the Tempo variable, construct a frequency histogram in Rguroo. Remember toproperly title and label the graph. Copy and paste this graph into your document.i)Describe the shape of the Tempo histogram in one sentence.j)For the Tempo variable, construct one horizontal boxplots in Rguroo. Remember toproperly title and label the graph. Copy and paste this graph into your document.k) Does the Tempo boxplot show any outliers? Answer this question in one sentence andidentify any outliers if they are present.21) Considering your interpretation of each variable’s graphs, is theory-based inference usingthe t-distribution appropriate for either variable (or both variables, or neither variable)?Answer the question and provide a reason for your response.m) If theory-based inference is not appropriate for one or both of the variables, presentanother possibility if the researcher still wanted to conduct statistical inference. Use oneto three complete sentences in your response.

The Following are Data for Systolic Blood Pressures, in mm of Mercury, of 12 Chimpanzees. 121, 125, 128, 134, 136, 138, 139, 141,144, 145, 149, 151 Based on this sample, do chimps have higher systolic blood pressure than humans, their closest relatives? Make sure you state the statistical hypotheses and conclusions, as well as the biological conclusions.

A recent study revealed that the average weight of babies born in the United States is normally distributed with a mean of 7.5 pounds. This number is lower than recent years and so researchers are interested in determining what factors are associated with lower birth weights. One researcher decides to look at the age of the mother to determine if younger mothers have babies that are significantly heavier or lighter than average. To study this the researcher collects data from 87 babies who were born to mothers between the ages of 16 and 18. Only one baby was measured per mother. Twins and other multiple births were excluded. The average weight for these babies was 7.3 pounds with a standard deviation of .6 pounds Select the two-tailed null hypothesis for this statistical analysis. The babies of young mothers will not be significantly different than the weight of babies in the general population. The babies of young mothers will be significantly lighter than the…
A researcher studying stress is interested in the blood pressure measurements of chief executive officers (CEOS) of major corporations. He has good reason to believe that the mean systolic blood pressure, u, of CEOS of major corporations is less than 130 mm Hg, which is the value reported in a possibly outdated journal article. He plans to perform a statistical test. He measures the systolic blood pressures of a random sample of CEOS of major corporations and finds the mean of the sample to be 120 mm Hg and the standard deviation of the sample to be 15 mm Hg. Based on this information, complete the parts below. (a) What are the null hypothesis H, and the alternative hypothesis H, that should be used for the test? H :0 O

A researcher studying stress is interested in the blood pressure measurements of chief executive officers (CEOs) of major corporations. He has good reason to believe that the mean systolic blood pressure, μ, of CEOs of major corporations is different from 132 mm Hg, which is the value reported in a possibly outdated journal article. He plans to perform a statistical test. He measures the systolic blood pressures of a random sample of CEOs of major corporations and finds the mean of the sample to be 124 mm Hg and the standard deviation of the sample to be 20 mm Hg.

People often say “Distance makes the heart fonder.” Interestingly, due to pandemic related lockdowns, some persons have been implicitly or explicitly indicating that it is indeed true as they have been struggling with their relationships due to lack of time apart from their partner. A researcher who is interested in such an issue decided to collect data on the level of rage/edginess that exist among a few couples due to lockdowns. Participants were asked to rank the level of hostility they think they have been exerting towards their partner due to having to spend more time than they usually do with them. The resulting data is presented on page two (2). 2 *14 is the highest level of hostility. Level of hostility Number of partners 0-1 4 2-3 11 4-5 8 6-7 20 8-9 25 10-11 12 12-13 12 13-14 4 a.

Dogsled drivers, known as mushers, use several different breeds of dogs to pull their sleds. One proponent of Siberian Huskies believes that sleds pulled by Siberian Huskies are faster than sleds pulled by other breeds. He times 4040 teams of Siberian Huskies on a particular short course, and they have a mean time of 7.77.7 minutes. The mean time on the same course for 4747 teams of other breeds of sled dogs is 6.26.2 minutes. Assume that the times on this course have a population standard deviation of 1.51.5 minutes for teams of Siberian Huskies and 1.61.6 minutes for teams of other breeds of sled dogs. Let Population 1 be sleds pulled by Siberian Huskies and let Population 2 be sleds pulled by other breeds. Step 1 of 2 : Construct a 95%95% confidence interval for the true difference between the mean times on this course for teams of Siberian Huskies and teams of other breeds of sled dogs. Round the endpoints of the interval to one decimal place, if necessary.
