Cats have a mean weight of 5.3 kg, which is normally distributed. A total of 9 cats from a cat colony are sampled and their weights are listed below. We want to determine, at α = 0.1 whether the cats have a different mean weight. Cat weights (kg): 7.1, 5.0, 5.5, 5.3, 6.2, 4.0, 7.4, 8.0, 5.3 (d) Determine tcrit and tsamp. (e) What decision do you make about your hypotheses? Briefly, interpret this answer in terms of the actual situation – say something specific about weights of the cats. (f) Construct a 90% confidence interval for the mean weight of a cat.
Rate of Change
The relation between two quantities which displays how much greater one quantity is than another is called ratio.
Slope
The change in the vertical distances is known as the rise and the change in the horizontal distances is known as the run. So, the rise divided by run is nothing but a slope value. It is calculated with simple algebraic equations as:
Cats have a
