scZoUnD [109]

Answer:

It measures the probability of observing your test statistic, assuming the null hypothesis is true.

Step-by-step explanation:

The p-value, also known as the probability value <u>measures the probability of observing your test statistic, assuming the null hypothesis is true.</u>

A low p-value means a higher chance of the null hypothesis to be true.

It lies between 0 and 1. A small p-value indicates fewer chances of the null hypothesis to be true.

Naddika [18.5K]

Answer:

Hi your question is incomplete attached below is the complete question

answer : p ( X < 725 )  = 0.0116

Step-by-step explanation:

Given data:

Average life of bulbs (μ  ) = 750 hours

standard deviation (б ) = 55 hours

n ( sample size ) = 25

X = 725  

<u>Probability that the mean life of a random sample of 25 bulbs will be less than725 hours </u>

p ( X < 725 ) = p (( X - μ )/ б √n  <  725 - 750 / 55√25 )

                     = P ( Z > - 2.27 )

Hence P ( X < 725 ) = 0.0116  ( using Z-table )

Step-by-step explanation:

y + 3x + 4y + 2x + 3y +3x

<em>With</em><em> </em><em>this</em><em> </em><em>we</em><em> </em><em>group</em><em> </em><em>x</em><em> </em><em>with</em><em> </em><em>x</em><em> </em><em>and</em><em> </em><em>y</em><em> </em><em>with</em><em> </em><em>y</em><em> </em><em>and </em><em>in</em><em> </em><em>ascending</em><em> </em><em>order</em><em> </em><em>so</em><em> </em><em>x</em><em> </em><em>comes</em><em> </em><em>before</em><em> </em><em>y</em>

3x+2x+3x

And the y with y

y+4y+3y

Which is;

3x+2x+3x+y+4y+3y

8x+8y
