Answer:
<em>The answer to the question is given below in the explanation section</em>
Explanation:
<em>From the question we recall the following</em>
<em>The mean: this is the the value at the center of the confidence interval which represents the quantity.</em>
<em>let Z* denotes when building the confidence level</em>
<em>]The mean = 289000, n = 36, standard deviation= 1342
</em>
<em>
Z* for 95% Confidence Interval = 1.96
</em>
<em>
The margin of error = 1.96*[1342/√(36)] = 438.39
</em>
<em>
The 95% Confidence Interval is given by:</em>
<em>
Lower CI = Mean - Margin of error = 289000 - 438.39 = 288561.61
</em>
<em>
Upper CI = Mean + Margin of error = 289000 + 438.39 = 289438.39
</em>
<em>When the sample is decreased to 20 Tesla owners, the confidence interval widens.</em>

Answer:
-$30,250 favorable
Explanation:
labor efficiency variance = (standard quantity - actual quantity) x standard labor cost
- actual quantity = 7,700 hours
- standard quantity = 9.9 hours x 1,000 units = 9,900
- standard labor cost = $13.70
labor efficiency variance = (7,700 - 9,900) x $13.70 = -$30,250 favorable variance
the variance is favorable, because less hours were actually used than forecasted
