taurus [48]

Answer:

$P= \left[\begin{array}{ccc}0.5&0.25&0.25\\0.25&0.5&0.25\\0.25&0.25&0.5\end{array}\right]$

Step-by-step explanation:

let a, b and c be the type of foods used in trail.

Example matrix combination for (1,1) is (a,a) is 0.5. Another Example for (1,2) is (a,b) is 0.25.

The diagonals are (a,a), (b,b) and (c,c) which means same food in two trails and its probability is 0.5. the rest would be 0.25

Therefore, stochastic matrix would have 3 by 3 matrix such as (a,a), (a,b) .... (c,c)

$\left[\begin{array}{ccc}0.5&0.25&0.25\\0.25&0.5&0.25\\0.25&0.25&0.5\end{array}\right] \\$

Mira's gross pay is $1846.

Effectus [21]

Answer:

Total FICA tax deducted from gross pay is $ 141 .22 .

Step-by-step explanation:

As given

Mira's gross pay is $1846.

The Social Security tax is 6.2% of gross pay.

6.2% is written in the decimal form.

$= \frac{6.2}{100}$

= 0.062

Social Security tax = 0.062 × Gross pay

= 0.062 × 1846

= $ 114.452

As given

The Medicare tax is 1.45% of gross pay.

1.45% is written in the decimal form .

$= \frac{1.45}{100}$

= 0.0145

Medicure tax = 0.0145 × Gross pay

= 0.0145 × 1846

= $ 26.767

Total FICA tax deducted from Gross pay = Social Security tax + Medicure tax

= $114.452+ $26.767

= $141.219

= $141.22 (Approx)

Therefore the total FICA tax deducted from gross pay is $ 141 .22 .

Determine whether the underlined value is a parameter or a statistic. The average age of men who had walked on the moon was 39 y

just olya [345]

Answer:

A. The value is a parameter because the men who had walked on the moon are a population.

Correct option the value reported represent the mean for all the individuals in the population of interest and for this reason represent a parameter.

Step-by-step explanation:

For this case we know that the average age of men who had walked on the moon was 39 years, 11 months, 15 days.

So then we need to assume that this value was calculated from the average of all the mean who walked on the moon, so then we have a population represented by a parameter.

And let's analyze one by one the possible options given:

A. The value is a parameter because the men who had walked on the moon are a population.

Correct option the value reported represent the mean for all the individuals in the population of interest and for this reason represent a parameter.

B. The value is a parameter because the men who had walked on the moon are a sample.

The value represent a parameter but the reason is not because represent a sample, is a parameter because represent the population of interest.

C. The value is a statistic because the men who had walked on the moon are a sample.

False the men who had walked on the moon are a population since they know the information about the men who walked on the moon and not represent a sample for this case.

D. The value is a statistic because the men who had walked on the moon are a population.

False the men who had walked on the moon are a population since they know the information about the men who walked on the moon, and if is a population then can't be a statistic.
