I think that you should try to involve yourself in their interests. Find a way to play with them because, as it seems, you want to maintain a friendship with this person, but want to be more involved in their life. I hope this helps <3

Suppose a large shipment of laser printers contained 22% defectives. If a sample of size 276 is selected, what is the probabilit

Mrrafil [7]

Answer:

The probability that the sample proportion will differ from the population proportion by less than 6% is 0.992.

Step-by-step explanation:

According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.

The mean of this sampling distribution of sample proportion is:

$\mu_{\hat p}=p\\\\$

The standard deviation of this sampling distribution of sample proportion is:

$\sigma_{\hat p}=\sqrt{\frac{p(1-p)}{n}}$

The information provided is:

$p=0.22\\n=276$

As the sample size is large, i.e. <em>n</em> = 276 > 30, the Central limit theorem can be used to approximate the sampling distribution of sample proportion.

Compute the value of $P(\hat p-p$ as follows:

$P(\hat p-p$

Thus, the probability that the sample proportion will differ from the population proportion by less than 6% is 0.992.

PLEASE HELP QUICK

<h3>Answer: Obtuse</h3>

This is because the lower left angle is larger than 90 degrees. This is assuming the triangle is drawn to scale (i.e. drawn accurately).

Any time there's an angle larger than 90, the triangle will be obtuse. If there's one angle exactly 90, then it's a right triangle. Otherwise, the triangle is acute (when all angles are smaller than 90).
