Billie wishes to test the hypothesis that overweight individuals tend to eat faster than normal weight individuals. To test this hypothesis, she has two assistance sit in a McDonalds restaurant and identify individuals who order the Big Mac Special (Big Mac, fries, and Coke) for lunch. The Big Mackers, as they are affectionately called by the assistants, are classified as overweight, normal weight or neither overweight nor normal weight. The assistants identify 10 overweight and 20 normal weight Big Mackers. The assistants record the amount of time it takes for the individuals to complete their Big Mac special meals.

After growth ceases, the number of fat cells may continue to increase if energy balance is (positive/reverse/negative/consistent) 3. Obese individuals generally have more (protein/pyruvate/lipoprotein hydrase/lipoprotein lipase) activity in their fat cells than normal weight individuals.

A diet doctor claims Australians are, on average, overweight by more than 10kg. To test this claim, a random sample of 100 Australians were weighed, and the difference between their actual weight and their ideal weight was calculated and recorded. The data are contained in the Excel file Weights.xlsx. Use these data to test the doctor's claim at the 5% level of significance.

A developmental psychologist suspects that first-born children tend to develop language skills faster than their younger siblings. An explanation for the phenomenon is that first-borns have undivided attention from their parents. As such, it is reasonable that twins and triplets have slower language development than single children. The psychologist collects measures of language skills for each child at age 3 in participating families. The data are below. What can the psychologist conclude with an α of 0.05? single twins triplets...

researcher wishes to test the claim that the average weight of an adult elephant is 12500 pounds. The researcher collected a sample of 33 adult elephants. The sample average for the weight of the elephants was 12200 pounds. The population standard deviation is believed to be 720 pounds. With alpha = 0.06, is there enough evidence to reject the claim. a) Is this a test that uses, z-scores, t-scores, or chi-squared values? b) [2 points] Does this problem involve proportions?...

First-born children tend to develop language skills faster than their younger siblings. One possible explanation is that they have undivided attention from their parents. If this is correct, then triplets should be slower. The following hypothetical data demonstrate potential measure of language skill from such a study. Do the data indicate significant differences?
