Answer:
Step-by-step explanation:
Sample mean x bar = 98.9
Std dev s = 0.62
Sample size n = 106
Std error = 
Since population std deviation not known we can use t critical value.
t critical for 99% with df = 105 is 1.98
Margin of error = ±1.98(0.0602) =±0.1192
Confidence interval for sample mean = (98.9±0.1192)
=(98.781, 99.019)
2) Sample mean confidence interval suggests that sample mean is different from the population since 98.6 is not contained in the confidence interval.
3) Population interval confidence mean would be
98.6±0.1192
=(98.4808, 98.7192)
The net would be 51 feet long to stretch from one side of the court to the other
<h3>What are scaled drawings?</h3>
Scale drawings are drawings that shows a diagram with another proportional dimensions
The scale ratio of the diagram is given as:
Scale = 1 inch = 12 feet
The length of the net is given as:
Length = 4.25 inches
So, the actual length of the net is:
Evaluate the product
Hence, the net would be 51 feet long, if stretched across the court

Answer:
N = 8
Step-by-step explanation:
(12 + 3) - 7 = N
=> N = (12 + 3) - 7
=> N = 15 - 7
=> N = 8
<span>Which of the following inequalities is correct?
-9 ≥ -7 is wrong as 9>7 but -9 < -7
-10 > |-10| is wrong as </span>|-10|= 10<span>
6 ≤ |-6| is right cause </span>|-6| =6 and we have 6=6 or <span>6 ≤ |-6| is also right</span><span>
0 < -13 is totally wrong
