Answer: (B) Increase the significance level to decrease the probability of Type I error.
Step-by-step explanation:
Step 1. The General Equation of a straight line is
Y = Mx + C where
M is the slope and
C is that point on the y axis where the curve cuts that axis (where x = 0)
In this case we are told that M = (3/4)
Our equation is now Y = (3/4)X + C ••• Equ 1
We are told that this curve passes through Point ( x, y ) = ( 8, -1 ).
Substitute these values of x, and y into Equ 1 to find C.
Y = (3/4)X + C or
( -1 ) = ( 3/4 )*( 8 ) + C or
( -1 ) = ( 6 ) + C or
C = ( - 7 )
Therefore the Equation of the Point Slope curve is
Y = ( 3/4 )X - 7

Answer:
311.25 hours ; almost 13 days
Step-by-step explanation:
actually you will not able to drive a car all the way around the earth (the Pacific and Atlantic oceans are really big).
but According to the calculation it would take you around 311.25 hours ( almost 13 days) to drive the 24,900 miles around the circumference of the earth at its widest point (the equator).
because we know ,
t=s/v
=(24,900/80)hours [ s= the circumference of the earth]
=311.25 hours [v=Velocity]
Answer:80students
Step-by-step explanation:
Using set notation concept,
n(U) be the total number of student = 200
n(AnS') be those that earned Bachelor in Art only= 120
n(A'nS) be those that earned Bachelor in Science only= 40
n(AnS) be students that earned both degrees.
Using the formulae below to calculate n(AnS) first;
n(AuS)=n(A'nS)+ n(AnS)+n(AnS')
200=40+n(AnS)+120
200=160+n(AnS)
n(AnS)=40
This shows that 40students earned bachelor in both degrees
Those that earned Bachelor in science degree will then be n(A'nS)+n(AnS) i.e 40+40 =80students.
NB: A' means complement of A(A not included)
'n' denote intersection and 'u' denote union.
Something angle nit sure ask your teacher
