Grasshoppers were randomly sampled from four isolated meadows and the sex of each insect was recorded. What analysis would you use to see if the proportion of males and females was the same among the meadows? Explain your answer. Would we use a One-factor ANOVA?

No, we will not use a One-factor ANOVA because One-factor ANOVA is used in the case when we have ratio/interval variables. In the given case, we want to check whether the proportion of males and females was the same for the four meadows or not.

We can perform a chi-square test for the difference in proportions to solve this problem.

If you have more questions you can send them to us and we will try our best to help you out.

Good luck with your studies!!!

Four runners were randomly sampled and it was found they ran 10, 14, 18, and 18 miles per week. Assuming the population is normally distributed, if we wish to test the claim that the mean running distance is at least 20 miles per week, what conclusion would you reach at the 10% level of significance? Show all the steps of hypothesis testing. You must state your conclusion in terms of the mean running time of runners.

Five different environments were chosen to compare the seed yield of four strains of a weed species. In each environment, four adjacent plots of approximately same fertility and moisture level were found and each strain was randomly assigned to a plot. At maturity, ten random samples were taken from each plot and the mean number of seeds per plant was recorded. These data are presented below:                                                                                                 Strain (I)                                     Environment (J)                   A         B         C         D                    ...

We are now also interested if a patient's weight has an effect on the drug's effectiveness. Patients were categorized as either underweight, overweight, or 'medium...

Silverman and Eals (1992) were interested in exploring sex differences in spatial ability. Based on a theory about sexual division of labor in evolutionary history, Silverman and Eals proposed that females may perform better than men on tasks of spatial memory. In one test, 20 women and 21 men were placed in a room in which there were a number of objects. Later, they were asked to recall the objects in the room and where they were. Women remembered an...
