A    sports    psychologist    wants    to    compare    the    running    time    for    athletes vs    non-athletes    while    running    1    mile.    He    collects    data    from    226    non-athletes    and    166    athletes and    analyzes    it    using    SPSS.

uppose Laura, a facilities manager at a health and wellness company, wants to estimate the difference in the average amount of time that men and women spend at the company's fitness centers each week. Laura randomly selects 13 adult male fitness center members from the membership database and then selects 13 adult female members from the database. Laura gathers data from the past month containing logged time at the fitness center for these members. She plans to use the data to estimate the difference in the time men and women spend per week at the fitness center. The sample statistics are summarized in the table. Population Populationdescription Population mean(unknown) Samplesize Sample mean(min) Sample standarddeviation (min) 1 male ?1 ?1=13 ?⎯⎯⎯1=132.5 ?1=45.3 2 female ?2 ?2=13 ?⎯⎯⎯2=108.7 ?2=31.1   df=21.256 The population standard deviations are unknown and unlikely to be equal, based on the sample data. Laura plans to use the two-sample ?-procedures to estimate the…

Most vertebrate adult body sizes remain constant or increase throughout their lives.  Marine iguanas are different in that they can actually decrease in size, in periods of low food availability.  Examine the data set here, and test the hypothesis that on average across time, iguana length changed (increased) by 1 mm.  Paste your R code in the answer box, and tell me your conclusion.  Data is here: https://github.com/lisamanne/biostats_data/raw/main/Iguana_lengths.csv DATA- Tributary,Species_upstream,Species_downstream I��,14,19 Juta�,11,18 Japur�,8,8 Coari,5,7 Purus,10,16 Manacapuru,5,6 Negro,23,24 Madeira,29,30 Trombetas,19,16 Tapaj�s,16,20 Xingu,25,21 Tocantins,10,12

could you provide an example please?

Measuring the height of a California redwood tree is very difficult because these trees grow to heights of over 300 feet. People familiar with these trees understand that the height of a California redwood tree is related to other characteristics of the tree, including the diameter of the tree at the breast height of a person. The data in the table represent the height (in feet) and diameter (in inches) at the breast height of a person for a sample of 21 California redwood trees. Interpret the meaning of the coefficient of determination in this problem. Perform a residual analysis on the results and determine the adequacy of the model. Determine whether there is a significant relationship between the height of redwood trees and the breast height diameter at the 0.05 level of significance.

UPDATED – Use this version! From part 2 of this assignment, you know that gestational diabetes affects #+1 percent of the population in our patient’s age group. Many women in this age group have decided to follow a special diet, which is advertised as being especially nutritious for the baby. One  clinic has 53 pregnant women who have elected to follow this diet. Out of these women, #+3 percent of them  have developed  gestational diabetes.  Use a 5% significance level to determine if this rate is higher than the #+1 percent level in the general population.  Show all work and include screen shots of any Excel template pages you use. Include the following.   A formal statement of the null and alternative hypothesis for your test. Make sure to include correct statistical notation for the formal null and alternative, do not just state this in words.    Screen shots of any Excel Template pages you use.   An interpretation of your p-value including A statement saying whether you…

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.
