Colton makes the claim to his classmates that less than 50% of newborn babies born this year in his state are boys. To prove thi

alexdok [17]

Answer:

Null hypothesis: $p \leq 0.5$

Alternative hypothesis: $p > 0.5$

The statistic is given by:

$z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}$ (1)

Replacing we got:

$z=\frac{0.512-0.5}{\sqrt{\frac{0.5(1-0.5)}{344}}}=0.445$

Step-by-step explanation:

Information given

n=344 represent the random sample taken

X=176 represent the anumber of boys babies

$\hat p=\frac{176}{344}=0.512$ estimated proportion of boys babies

$p_o=0.5$ is the value that we want to check

z would represent the statistic

$p_v$ represent the p value

Hypotheis to verify

We want to check if the true proportion of boys is less than 50% then the system of hypothesis are .:

Null hypothesis: $p\leq 0.5$

Alternative hypothesis: $p > 0.5$

The statistic is given by:

$z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}$ (1)

Replacing we got:

$z=\frac{0.512-0.5}{\sqrt{\frac{0.5(1-0.5)}{344}}}=0.445$

Here,

8-2x=20

or,8-20=2x

or, -12=2x

or, x=-12/2

therefore,

3 gallons in 15 seconds would be 3/15

so for 1 gallon 15/3 = 5

it would be 1 gallon every 5 seconds so 1/5

given that interior angle of a regular polygon is five times of its exterior angle, calculate the size of interior angle of the

Natali5045456 [20]

Answer:

Step-by-step explanation:

Let the exterior angle = x

Interior angle = 5x

x + 5x = 180 { interior angle and exterior angle are linear pair}

6x = 180

x = 180/6

x = 30

Interior angle = 5*30 = 150
