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.
