An unfair coin with Pr[H] = 0.75 is flipped. If the flip results in a head, a student is selected at random from a class of si

Agata [3.3K]

Answer:

72.73% probability of selecting a girl, given the flip resulted inheads

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Coin resulted in heads

Student is selected at random from a class of six boys and sixteen girls.

Desired outcomes:

16 girls, so $D = 16$

Total outcomes:

16+6 = 22, that is, 22 students, so $T = 22$

Probability:

$P = \frac{16}{22} = 0.7273$

72.73% probability of selecting a girl, given the flip resulted inheads

How do you invert and multiply to divide 2/3÷4

Ira Lisetskai [31]

2/3 ÷ 4

2/3 ÷ 4/1

We invert the 4/1 to 1/4 and multiply out.

2/3 × 1/4

= 1/3 × 1/2 2 into 4 is 2.

= 1/(3 × 2)

= 1/6

A company manufacturing computer chips finds that 8% of all chips manufactured are defective. In an effort to decrease the perce

neonofarm [45]

Answer:

The correct value of the Z-statistic is z = -1.56

Step-by-step explanation:

A company manufacturing computer chips finds that 8% of all chips manufactured are defective.

This means that the null hypothesis is:

$H_{0}: p = 0.08$

A hypothesis test is performed to determine if the additional training was effective in lowering the defect rate.

This means that the alternate hypothesis is:

$H_{a}: p < 0.08$

z-statistic:

$z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

In which X is the sample mean, $\mu$ is the value tested at the null hypothesis, $\sigma$ is the standard deviation and n is the size of the sample.

0.08 is tested at the null hypothesis:

This means that $\mu = 0.08, \sigma = \sqrt{0.08*0.92}$

After training was implemented, a sample of 450 chips revealed only 27 defects.

This means that $n = 450, X = \frac{27}{450} = 0.06$

The correct value of the Z-statistic is

$z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

$z = \frac{0.06 - 0.08}{\frac{\sqrt{0.08*0.92}}{\sqrt{450}}}$

$z = -1.56$

Danny invests $10,000 in a savings account that pays 3.5% simple interest. If Danny does not make any additional deposits or wit

SashulF [63]

Answer:

Danny will have 12,450 in his savings account

Step-by-step explanation:

P is the principal amount, $10000.00.

r is the interest rate, 3.5% per year, or in decimal form, 3.5/100=0.035.

t is the time involved, 7....year(s) time periods.

So, t is 7....year time periods.

To find the simple interest, we multiply 10000 × 0.035 × 7 to get that:

The interest is: $2450.00

10000.00 + 2450.00 = 12450.00.
