Answer:
H 0 : p ≤ 0.4 H a : p > 0.4
And based on the alternative hypothesis we can conclude that we have a right tailed test
Step-by-step explanation:
Data given
n=300 represent the random sample size
estimated proportion of people with cats
is the value that we want to test
represent the significance level
z would represent the statistic
represent the p value
Null and alternative hypothesis
We want to test if the true proportion of people with cats is higher than 0.4, so then the best alternative is:
Null hypothesis:
Alternative hypothesis:
H 0 : p ≤ 0.4 H a : p > 0.4
And based on the alternative hypothesis we can conclude that we have a right tailed test
The statistic is given by:
(1)
Replacing we got:
The correct order of the cards will be D = -4, C=-2, A = -1 and B = 1.
The complete question is attached with the answer below:
<h3>What is an algebraic sum?</h3>
An algebraic sum of two or more numbers or quantities stated in terms of their signs (as + or -) as per the additions rules in algebra.
The calculation of the numbers on each card will be calculated as:-
A = 1 + 4 -6 = -1
B = 2 - 7 + 6 = 1
C = 4 - 8 + 2 = -2
D = 6 - 3 - 7 = -4
From the above calculation, the lower to the higher arrangement of the cards will be:-
D = -4, C=-2, A = -1 and B = 1.
Therefore the correct order of the cards will be D = -4, C=-2, A = -1 and B = 1.

#SPJ1
65 x 4 = 260 cm was left after tying the parcel
260 + 45 = 305 cm was the total length
Answer:
I believe C. would be the correct answer.
Answer:
we know that
10*pi/3------> convert to degrees------> 10*180/3=600 degrees
600=360+240
240 degrees belong to the III quadrant
so
the x-coordinate is negative
the y-coordinate is negative
240°=180°+60°
60 degrees is the angle to find the terminal point
let
∅=60°
in the unit circle
r=1 units
x=-r*cos ∅----> x=-cos 60------> x=-(1/2)
y=-r*sin ∅----> y=-sin 60------> y=-(√3)/2
the point is
-1/2,-√3/2
the answer is the option A
