For this case we must convert from yards to inches. By definition we have to:
1 yard equals 36 inches
Making a rule of three we have:
1 yd ----------> 36 in
5 yd ----------> x
Where "x" represents the number of inches equivalent to 5 yards.
Thus, 5 yards represents 180 inches.
Answer:
180 inch
The correct option is 20.
The score found for the sample is 20.
<h3>What is Standard error?</h3>A standard error is a statistic that is applied to test the distribution of data. This metric is comparable to standard deviation. We can calculate the standard error if we know the sample size & standard deviation. It assesses the mean's precision.
Now, according to the question;
Sample mean;
Sample variance;
Thus,
Standard error SE = 1
The amount of scores with in sample must be determined here.
The standard error formula is as follows:
We might rearrange the formula as follows:
Substituting the values;
The sample's number of scores n = 19.98 = 20 (round up)
Therefore, the scores are in the sample is 20.
