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.
Since, <span>point K is the image of point J under a reflection across line L.
The distance, JM = MK
</span>Hence, 2x + 4 = 4x - 6
4x - 2x = 4 + 6
2x = 10
x = 5
Also refrection of a point across a line form an angle of 90 degrees at the point of refrection.
i.e. 3y - 30 = 90
3y = 90 + 30 = 120
y = 120 / 3 = 40
Therefore, the value of y is 40.
