Help me find the Domain Range X-intercepts Y-intercepts

The X-intercepts are the places where the line crosses the x axis which is the one that goes along so they would be 5 and -5.
the Y-intercepts is the place where the lines cross the y axis which is the one that goes up. so for this question it is 5.

i’m not sure about the domain or the range.

please mark me brainiest

-1.5

Step-by-step explanation:

When population standard deviation is known, then the formula to find the z-test statistic for population mean is given by :-

, where n= Sample size.

= Population mean

= Sample mean

= Population standard deviation.

As per  given , we have  (average infants contracted typhoid each month)

n= 4 (No. of months)

Then , the value of the appropriate test statistic will be :

Hence, the value of the test statistic = -1.5
