The Cubs have won 44 baseball games and have lost 65 games. They have 53 games remaining. At least how many of the remaining 53

Nimfa-mama [501]

More than 50% would be 50% of the total games plus one win.
In total, there are 162 games.
44+65+53=162
50% of 162 equals 81.
The cubs must win 82 games. If they have won 44 games so far, then 82-44=36
They must win at least 56 games to have a winning season.

Hope I got it right for your sake.

In a random sample of fivefive microwave ovens, the mean repair cost was $75.0075.00 and the standard deviation was $13.0013.

Radda [10]

<h2>Answer with explanation:</h2>

As per given , we have

Sample size : n= 5

Degree pf freedom = : df= 5-1=4

$\mu=\$75.00$

$\sigma=\$13.00$

Significance level for 90% confidence = $\alpha=1-0.90=0.1$

Using t-value table , t-critical value for 90% confidence:

$t_{\alpha/2, df}=t_{0.05, 4}=2.132.$

Margin of error of $\mu$ : $E=t_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}\\\\(2.132)\dfrac{13}{\sqrt{5}}=12.3949720129\approx12.39$

Interpretation : The repair cost will be within $12.39 of the real population mean value $\mu$ 90% of the time.
