zChest -> (91.2-75)/4.8=-3.4zWaist -> (80.9-56.5)/9.8≈-2.5zHips -> (93.7-72)/6.8≈-3.2It would be Ken's chest because the difference between the doll and an averaged human male is the greatest

2.)
zChest -> (82.3-90.3)/4.7≈-1.45zWaist -> (40.7-69.8)/4.7≈-6.19zHips -> (72.7-97.9)/5.4≈-4.7
Yes because the waist is far too thin compared to an averaged human woman

3.)
zJill -> (680-500)/100=1.8zJack -> (27-18)/6=1.5

4.)
It would be Jill because she has the higher z-score

Children inherit their blood type from their parents, with probabilities that reflect the parents' genetic makeup. Children of J

anygoal [31]

Answer:

$n = 4, p = 0.25$

Step-by-step explanation:

We are given the following in the question:

We treat adult having blood type A as a success.

P(Blood type A) =

$p=\dfrac{1}{4} = 0.25$

Then the number of Children of Juan and Maria who have blood type A follows a binomial distribution as there are

n independent trial.
Each trial have to outcomes(Blood type A or not)
Probability of success is same for each success

Here,

$P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}$

where n is the total number of observations, x is the number of success, p is the probability of success.

Thus, for the given binomial distribution,

$n = 4, p = 0.25$

Suppose an automobile manufacturer designed a radically new lightweight engine and wants to recommend the grade of gasoline that

Deffense [45]

Answer:

The F-statistic used to test the hypothesis that the miles per gallon for each fuel are the same is 4.07.

Step-by-step explanation:

There are four treatments in the data given, i.e. k = 4.

Total number of observations, n = 12.

Note: degrees of freedom is denoted as df.

For treatment, the degrees of freedom = k-1 = 4-1 =3 df.

The total degrees of freedom = n-1 = 12-1 = 11 df.

The error in degrees of freedom = df (total) - df(treatment)

The error in degrees of freedom = 11 - 3 = 8 df

At α = 0.05 level,from the F table, the F-statistic with (3 , 8)df is 4.07.

Therefore, the F-statistic used to test the hypothesis that the miles per gallon for each fuel are the same is 4.07.
