This function will create a parabola that opens upwards. I’m not entirely sure what I was supposed to answer. Hopefully this covered it. I’ll attach an image of the parabola in case I missed anything.
Answer:
What is the probability the mean of his sample will be between $70.00 and $80.00? = 64/64 =1
s1) = 99% =z score = 127/128
s2)64/64 = 1
s3)95% of 64 = 123/128
s4) p) step 3 = 95% of 64 = 60.08 /64 = 60/64 = 93.75%
s5) P)of 2+4 = 283/292 = 96.92%
Do we have to give it in a percentage? Or....
I don’t really know if this is a question but if ur asking the variable of an unknown number then it’s x??
The answer is -6.57
In order to get this, we just treat it as a subtraction problem. Adding a negative number is the same thing as subtraction.
1.7 - 5 = -3.3
Now do the second part
-3.3 - 3.27 = -6.57
