Explanation:
We are given:
sample size= n = 45
sample mean = x = 61,300
sample standard deviation =18,246
Since the population standard deviation is not known we will use t distribution to find the confidence interval.
Confidence interval = 99%
Degrees of freedom= n - 1 = 45 – 1 = 44
Critical t value = 2.692
The 99% confidence interval will be:
Thus, the 99% confidence interval for the population mean is:
53978 to 68622
Answer:
2.5% of $80,000=$2,000
The Smiths pay $2,000 in school taxes per year.
Explanation:
100%=$80,000
10%=$80,000(100%)/10=$8,000(10%)
5%=$8,000(10%)/2=$4,000(5%)
2.5%=$4,000(5%)/2=$2,000(2.5%)
