Answer:
-3
Step-by-step explanation:
Born: 7.45 pounds
gains: 6.4 oz a week
time: 1.5 months
6.4 + 6.4 + 6.4 + 6.4 + 6.4 + 6.4 = 38. 4 oz
38.4 oz = 2.4 punds
7.45 + 2.4 = 9.85
Answer: b. Yes
Step-by-step explanation: Confidence Interval for a population proportion is calculated as:
p ±
where
p is the sample proportion
n is sample size
z is z-score, in this case, as it is 95%, z-score=1.96
Calculating confidence interval:
p = 0.3248
0.3248 ±
0.3248 ±
0.3248 ± 0.0425
Interval: 0.2823 < μ < 0.3673
The interval means we are 95% sure the true mean is between 0.2823 and 0.3673. As the campaign claims a proportion of no more than 0.32 of the voters wants to see Mayor Waffleskate defeated and the number is in the confidence interval, the claim is supported.
