A certain intelligence test has an N(100, 100) distribution. To see whether intelligence is inherited, tests are given to the el

Anettt [7]

Answer:

Follows are the solution to the given choices:

Step-by-step explanation:

In choice a:

$\to \mu = 100$

In choice b:

$\to \mu \neq 100$

In choice c:

$\to \ pop \ average=100 \\\\ \to \ variance \ of \ pop = 100 \\\\\to pop \ \ \sigma = \sqrt {(!00)} \\$

= 10

$z= \frac{\bar x - \mu}{ \frac{\sigma}{\sqrt(n)}}\\\\$

$=\frac{(105-100)}{\frac{10}{ \sqrt(16)}}\\\\=\frac{(5)}{ \frac{10}{4}}\\\\=\frac{5}{ \frac{5}{2}}\\\\= \frac{10}{5}\\\\=2$

$\to p==2\times (1- \ righttail)\\\\\to \ righttail\ \ p = \text{NORM.S.DIST(2,TRUE)}$

$=0.977249868$

$\therefore \\P=2 \times (1-0.9772)\\\\P=0.0455\\\\P$

Null hypothesis to dismiss

Alternate solution assumptions embrace

There is really no valid proof at the 5% stage that

Knowledge is legacy

In choice d:

Possibly information such as this reflect a sample population with such a true p = 0.0455 meaning in the hypothesis

u is around 100.

Solve the problem using 6.2%, up to $128,400 for Social Security tax and using 1.45%, no wage limit, for Medicare tax.

maksim [4K]

Based on the social security tax rate and the Medicare tax, the monthly Social security is $109.12 and the Medicare tax is $25.52.

<h3>What is monthly social security act?</h3>

Graham, C. has not reached the $128,400 threshold for social security so the Social Security tax withholding for the month will be:

= Monthly salary x Social security rate

= 1,760 x 6.2%

= $109.12

The Medicare has no limit and so will be:

= 1,760 x 1.45%

= $25.52
