Question
Prednisone is a corticosteroid used to treat many inflammatory disease such as asthma, ulcerative colitis or acne However, prolonged use of the drug can cause patients to develop osteoporosis, low bone density. Recently a new drug, prednisone has been developed that acts as anti-inflammatory with fewer side effects To compare the drugs impact on bone density a study was done in which two groups of cats received equivalent does of prednisone or prednisone for in equivalent time period. At the end of the treatment period the bone density of both groups was measured. The researchers want to determine If the bone density between the two treatment groups was equivalent, or if the prednisone treatment group had a greater bone density than the prednisone treatment group. Assume unequal variance between treatment groups (specify type 3 t-test in your spreadsheet software), What is the null hypothesis of this experiment? a there is no difference m bone density between cats given prednisone and those given prednisolone b. the bone density of cats given prednisone will be greater than that of cats given prednisolone c. the bone density of cats given prednisone will be less than that of cats given prednisolone The study was conducted and the bone densities from the cats at the end of the treatment period were recorded (link to data is below). Each measurement represents an individual cat that was given either Prednisone or Prednisone. Now the researchers want to be use a t-test to see if the data show any differences between the treatments. Using Google Sheets (or another spreadsheet if you have a favorite). Calculate the t-test probability. To do this in Google Sheets, the formula is the little more also this Copy and paste your calculated t-test probability here: Based on the t-test probability you would the null hypothesis.
Explanation / Answer
1)
Answer: A
That is, there is no difference in bone density between cats given prednisone and those given prednisolone.
