Answer:
7
Step-by-step explanation:
first put them in order
5,6,6,8,9,9
now the ones that are in the middle are 6 and 8 so we find the average by adding them then dividing by 2
6+8=14/2=7
The sample size suggested by this statement is 664 option second is correct.
<h3>What is the margin of error(MOE)?</h3>
It is defined as an error that provides an estimate of the percentage of errors in real statistical data.
The formula for finding the MOE:

Where Z is the z-score at the confidence interval
s is the standard deviation
n is the number of samples.
At 99% confidence Z = 2.576
By using the MOE formula:
0.05 = 2.376×√(0.5(0.5)/n)
After calculating
n = 663.57 ≈ 664
Thus, the sample size suggested by this statement is 664 option second is correct.

Hey there!
At first, Josh has 30 keys.
Then, he loses 3 keys.
30 keys - 3 keys = 27 keys
After that, Josh finds 7 keys.
27 keys + 7 keys = 34 keys
Josh will have a total of 34 keys.
Hope this helps! Have a great day!
