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

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.

In west Texas, water is extremely important. The fllowing data represent pH levels in ground water fr a random smple of 102 west Texas wells. A pH and a pH above 7 is alkaline. Scanning the data, you can see that water in this region tends to be hard (alkaline). Too high a pH means the water is unus expensive treatment to make it usable.+ These data are also available for download at the Companion Sites for this text. For convenience, the data are p increasing order. x: pH of Ground Water in 102 West Texas Wells 7.0 7.0 7.0 7.0 7.0 7.0 7.0 7.0 7.1 7.1 7.1 7.1 7.1 7.1 7.1 |7.1 7.1 |7.1 7.2 | 7.2 7.2 | 7.2 |7.2 7.2 7.2 7.2 7.2 7.2 7.3 7.3 7.3 7.3 7.3 7.3 7.3 7.3
