Answer:
37.5% decrease
Step-by-step explanation:
The percentage change is given by the formula ...
pct change = ((new price) -(original price))/(original price) × 100%
= (50 -80)/80 × 100%
= -3/8 × 100% = -37.5%
The negative sign indicates a decrease.
The decrease in price is 37.5%.

Answer:
5.2 inches
Step-by-step explanation:
The diameter of small Nerf balls follows normally distribution with mean 5.2 inches and standard deviation 0.08 inches.
We have to calculate the mean of sampling distribution when 20 balls are selected randomly.
Here, μ=5.2 and σ=0.08.
We know that mean of sampling distribution for mean is equal to the population mean.
mean of sampling distribution for mean= μxbar=μ= 5.2
Thus, mean of the sampling distribution of the sample mean is 5.2 inches
