Answer:

Step-by-step explanation:

The pediatrician said that the z-score for the boy's height, relative to other 2-year-olds in the country, was 1.59

He explains to the parents of the boy, that the extreme 5% of cases often require special attention.

(A) Does this child fall into that group?

Yes, this child falls into that group. He is among the extreme 5% of cases at the tail of the distribution.

(B) What do you need to assume about the heights of 2-year-olds, in order to find your answer to part (A)?

Assume that the distribution of heights is skewed, the heights are independent of one another, and the number of heights is very large.

Your little brother just learned how to flip and catch a coin. He believes that by catching the coin in mid-air, he can influenc
coldgirl [10]
<h2>Answer explanation:</h2>

If a coin is fair then it has two faces , one is heads and the another is tails.

The probability getting any favorable outcomes is given by the formula :-

\dfrac{\text{Number of favorable outcomes}}{\text{Total outcomes}}

So the factor effecting probability is just the number of  favorable outcomes and total outcomes.

If a coin is tossed then the probability of getting heads will be :-

P(H)=\dfrac{1}{2}=0.5=50\%

To get heads always this should be 1 , which can be happen if number of  favorable outcomes is equal to total outcomes.

i.e. Number of heads = Number of total outcomes, this means coin should be biased.

Catching the coin in mid-air can never be a factor for this.

Therefore, the little brother's theory is false.

Answer:

The degrees of freedom for this sample are 27.

The sample size to get a margin of error equal or less than 0.3656 is n=4450.

Step-by-step explanation:

The degrees of freedom for calculating the value of t are:

df=n-1=28-1=27

With 27 degrees of freedom and 95% confidence level, from a table we can get that the t-value is t=2.052.

The sample size to get a margin of error equal or less than 0.3656 can be calculated as:

MOE=t\cdot s/\sqrt{n}\\\\n=\left(\dfrac{t\cdot s}{MOE}\right)^2=\left(\dfrac{2.052\cdot 11.8841}{0.3656}\right)^2=66.7^2\\\\\\n=4449.13\approx4450
