Step-by-step explanation:
Given points are (-2,5) and (3,-17)
to find midpoint, use this formula
( x1+x2/2 , y1+y2/2)
where points are a(x1,y1) and b(x2,y2)
coming to the question,
midpoint is :
[ (-2-3)/2 , (5-17)/2 ]
[ -5/2 , -12/2 ]
[ -2.5 , -6 ]

C) 1.65
Step-by-step explanation:
A hypothesis used to test that

against the alternatives
not equal to 10
if null hypothesis is true, then distribution of test statics follow
for two sided alternatives hypothesis
, then P value is
(1)
a)significance level
from 1 eq we get
Therefore

from 1st equation we get
Therefore
FROM Z TABLE
C) significance level
from 1 eq we get
Therefore
FROM Z TABLE
