Answer:
Step-by-step explanation:
Amphetamine is a drug that suppresses appetite in most animals. To study the magnitude of this effect in rats a scientist randomly assigned thirty rats into three treatment groups to receive either a dose of amphetamine (2.5 or 5.0 mg/kg) or a control (saline, 0 mg/kg). Then food consumption was measured in grams per kilogram of body weight (g/kg) for the three-hour period after the injection.
A) Which of the choices on Canvas best represents the null/alternative hypothesis of this study?
µ1 = µ2
µ1 ≠ µ2
µ1 > µ2
µ1 < µ2
µ1 ≥ µ2
µ1 ≤ µ2
θ1 = θ2
θ1 ≠ θ2
θ1 > θ2
θ1 < θ2
θ1 ≥ θ2
θ1 ≤ θ2
ρ = 0
ρ ≠ 0
β = 0
β ≠ 0
The residuals of these data are consistent with a normal distribution.
These residuals of these data are not consistent with a normal distribution.
The variances of the response/residuals are the same for all values of x.
The variances of the response/residuals are not the same for all values of x.
