So I’m doing a research study to see if there is a significant
difference between male and female sedation time (how long it takes
the animal to go down- in minutes). I know the data won’t be super
reliable being that there are more males than females. But I need
help on what test needs to be ran with this type of data. This is

Suppose you want to determine whether there is a significant difference in mean test scores for females and males. The test is out of 600 points. Using the following hypotheses: Ho: U1 - U2 = 0 HA: U1 - U2 (not equal) 0 And alpha of 0.05 you obtain the following results t-test Two-sample assuming unequal variances Females Males Mean 525 487 Variance 3530.8 2677.818182 Observations 16 12 Hypothesized Mean Difference 0 df 25 t stat 1.803753 P (T<=t) one...

Some groups have clamored that the difference in expected lifespan between males and females is a result of social rather than biological factors. While we cannot determine that, we can examine if any notable difference exists between the average lifespans for men and women, at least in the USA. In a random sample, we found the average lifespan for American women was 80.6, and the average lifespan for American men was 76.3. We want to test the difference in the...

Do you view a chocolate bar as delicious or as fattening? Your attitude may depend on your gender. In a study of American college students, Rozin, Bauer, and Catanese (2003) examined the importance of food as a source of pleasure versus concerns about food associated with weight gain and health. The following results are similar to those obtained in the study. The scores are a measure of concern about the negative aspects of eating. Males Females n=9 n-15 M 33...

In this assignment, you will test for a significant difference between the average resting heart rate of males and the average resting heart rate of females in your heart rate data. You have observed that the mean rates are not exactly the same but are they significantly different? You may use either of the two methods for testing a hypothesis illustrated in Realizeit: compare the two confidence intervals or use the data analysis tool to run a two-sample test with...

Historically, the population of wolves in Canada have been found to have an average adult weight of 38.9 kilograms. The Canadian Wildlife Service believes that due to climate change, this may have increased. A random sample of 12 wolves is captured and weighed and the following results are obtained. Assume that the weights are normally distributed: 44.8, 40.7, 42.6, 46.8, 48.7, 35.4, 38.9, 39.5, 38.3, 48.9, 48.4, 38.4. At a 0.05 significance level, test the hypothesis that the average weight...

According to a Health of Boston report, female residents in Boston have a higher average life expectancy as compared to male residents (The Boston Globe, August 16, 2010). You collect the following sample data to verify the results of the report. You also use the historical (population) standard deviation of 8.2 years for females and 8.6 years for males. (You may find it useful to reference the appropriate table: z table or t table) Female Male −x1 = 81.1 −x2...
