Answer:
540
Step-by-step explanation:
3% of 6000 is 180. Multiply that by 3 years and you have your result.
Number of ppl that said they played hockey / total ppl =
495/2286 (simple division to turn to a decimal)
0.2165 (now multiply the decimal by 100 to get ur percent)
0.2165 * 100 = 21.65%...or if it needs to be rounded, it is 22%
Answer:
Option B - 0.02
Step-by-step explanation:
In this question, the p-value is used to tell us the probability that a difference of (0.88 – 0.68) which is 0.2 or greater would occur in the distribution of simulated differences. This is created done with the assumption that there is no true difference in the two populations.
Due to the fact that the researchers found the difference in proportions to be statistically significant, hence these results would rarely occur due to just the sampling variability and thus the p-value must be small.
Looking at the options, the p-value in Option (B) will be the correct response,l as it indicates that a difference of 0.2 or more would only occur about 2% of the time by chance alone provided the proportion who text were the same in the population of seniors and the population of freshmen. This resonates well with the claim that the difference in proportions is statistically significant.
Thus, Option B is the correct answer.
Answer:
6. 28pi
7. correct
Step-by-step explanation:
Formula for circumference: 2*pi*r
Formula for area: pi*r^2
So:
7: radius = diameter/2 = 4.8
4.8*4.8*pi = 23.04
8. not sure
