The concussion data set from dr Larry winners repository reported that 158 females of the 304 subjects who played soccer experienced a concussion, compared to 101 of males of the 254 subjects that also experienced a concussion from playing soccer . In the sample a larger amount of females experienced more concussions than males . Construct a 0.05 confidence level to test the claim that the percentage is enough to say the entire female population will experience more concussions than males while playing soccer ?

Here is a link to the data set collected by Dr. Hernandez. Her research team has a data set of the weight of fishes caught from both the contaminated lake and the pristine lake. Assume both of these data sets have equal variance. Perform the correct statistical test and determine the P value to test Dr. Hernandez's hypothesis. Report your answer for P rounded to four decimal places. Use formulas, functions, and the data analysis tool pack in Excel to...

Birth Weight Data Set 3 “Births” in Appendix B includes birth weights of 205 females, and the summary statistics are ¯x=3037.1 g x¯=3037.1 g and s = 706.3 g. Use a 0.01 significance level to test the claim that the population of birth weights of females is greater than 3000 g. Data set 3 : Data are from 400 births (first five rows shown here). For GENDER 0 = female and 1 = male. LENGTH OF STAY is in days,...

The data set for this question set (Tab Q1 in the Excel data file) comes from a research project that tracks the elderly residents in a community to monitor their cognitive function and general health. Based on the literature, education is considered a protective factor against dementia, and memory decline is usually the first sign of dementia. So the researchers would like to know whether education level (measured in number of years of formal schooling) is correlated with memory function...

  Assume that 18 subjects received one of three treatments and produced the data reported in Data Set B. Conduct a one-way ANOVA to see if the means of the three treatments are different on a statistically significant level. Complete an ANOVA table reporting the relevant SS, df, MS, and Fs. Also remember to include your critical value and whether you would reject your null hypothesis. Data Set B Treatment 1 Treatment 2 Treatment 3 50 60 70 55 60...
