Candy has observed 250 sports cars at an intersection and found that 15% did not make a complete stop. Candy tells you that the

Julli [10]

Answer:

The confidence level of the study is 99.9%

The confidence level is 99.9% of the margin error is 8%

Step-by-step explanation:

<u>Explanation</u>:-

Candy has observed 250 sports cars

The sample size 'n' = 250

Sample proportion 'p' = 15% = 0.15

The margin of error = 8% = 0.08

<em>The margin of error is determined by </em><em> = </em> $\frac{z_{\alpha }\sqrt{p(1-p)} }{\sqrt{n} }$ <em />

<em> </em> $0.08 X \sqrt{250} = z_{\alpha } \sqrt{0.15 (1-0.15)}$ <em />

$\frac{ 0.08 X \sqrt{250}}{ \sqrt{0.15 (1-0.15)}} = z_{\alpha }$

$z_{\alpha }= \frac{ 0.08 X \sqrt{250}}{ \sqrt{0.15 (1-0.15)}} = \frac{1.2649}{0.35707}$

$z_{\alpha } = 3.5431$

<u>Conclusion</u>:-

The z- score of 99.9% level of significance = 3.54 for two tailed test

<em>Hence the confidence level is 99.9% of the margin error is 8%.</em>

A package that is heavier than 11 lb. and 8 oz. will have a label that says "heavy" on it. Gloria packed 6 flower pots to send t

____ [38]

Answer:

No, the package will not be labeled "heavy"

Step-by-step explanation:

1) if you multiply 1lb. and 12 oz. by the number of flower pots(I'll be using the variable P), then the expression will be (1lb.P) (12oz.P).

2) then after you get the answer for that, which is 6lb. 72oz. and after that you'll have to add the weight of the packaging, which is 5oz. which the answer is 6lb. 77oz.

3) after, you will then have to get the number of pounds from the ounces if there are more than 16, which there are, so after you get the answer out of that, which is 4 and then you would have 13oz. leftover.

4) you would then have to add your 4lb. to your 6 that you already have, which would be 10lb.

Final) so in the end, you would have 10lb. 13oz.
