Answer:
16% is the percent of increase to the nearest whole-number percent.
Step-by-step explanation:
As the cost of a pound of nails increased from $2.17 to $2.52.
so dividing the 0.35 by 2.17 would give us the percetange of increase
- 0.35/2.17 = 0.16 which is 16%.
Therefore, 16% is the percent of increase to the nearest whole-number percent.
Answer:
0.1587
Step-by-step explanation:
Here, mean=μ=100 and standard deviation=σ=16.
We have to find P(average MDI scores of 64 children > 102)=P(xbar>102).
n=64
μxbar=μ=100
σxbar=σ/√n=16/√64=16/8=2
P(xbar>102)=P((xbar-μxbar)/σxbar>(102-100)/2)
P(xbar>102)=P(z>1)
P(xbar>102)=P(0<z<∞)-P(0<z<1)
P(xbar>102)=0.5-0.3413
P(xbar>102)=0.1587
Thus, the probability that the average is greater than 102 is 15.87%
