Answer with explanation:</h2>
Let 
be the population mean.
For the given claim , we have
Null hypothesis : 
Alternative hypothesis : 
Since alternative hypothesis is two-tailed , so the test is a two-tailed test.
Given : Sample size : n=220 ;
Sample mean: 
;
Standard deviation: 
Test statistic for population mean:
By using the standard normal distribution table of z , we have
P-value ( two tailed test ) : 
Since , the P-value is greater than the significance level of 
, it means we do not have sufficient evidence to reject the null hypothesis.

Answer:
0.4
Step-by-step explanation:
Probability = Favourable Outcomes / Total Outcomes
Probability (Blue socks drawn out) = Blue Socks pairs / Total Socks pairs
6 / ( 5 + 6 + 3 + 1 )
= 6 / 15
= 0.4
Answer:
14 + 25l + 6l^2
Step-by-step explanation:
(7 + 2i) (2 + 3i)
=> 14 + 4l + 21l + 6l^2
=> 14 + 25l + 6l^2
This is the correct answer
