Answer: See explanation
Step-by-step explanation:
The null hypothesis H0: The null hypothesis states that there is no relationship between the two things that are being considered.
The alternative hypothesis is contradictory to H0 and it explains that there is a relationship between the two selected variables.
Based on the question, the null hypothesis H0 is that the rating of car is equal to 46.7 miles per gallon. μ = 46.7 MPG
The alternative hypothesis Ha is that the rating of the car is not equal to 46.7 Miles per gallon. μ ≠ 46.7 MPG
Answer:
The answer is 4.
Step-by-step explanation:
There are 16 possible outcomes of this, and of those, only 4 of them result in the coin landing on heads and landing on a number that is greater than 4.
Answer:
a) 1/10
b) 110
Step-by-step explanation:
A) we start by getting the total number of rolls
That would be;
11 + 22 + 7 + 8 + 13 + 19 = 80
The frequency of getting a 4 is 8
The probability that the next roll will be a 4 is;
8/80 = 1/10
b) Firstly, we get the probability of getting a 2
We have this as:
22/80
So for 400 rolls, the number of 2’s will be;
22/80 * 400
= 22 * 5 = 110
Y = kx as y and x are directly proportional
6 = 10k
k = 0.6
y = 0.6x
18 = 0.6x
x = 30
Here are the coordinates:
(60, 105)
(62, 114)
(64, 124)
(66, 131)
(68, 139)
(70, 149)
(72, 158)
Step-by-step explanation: All you have to do is take the values for y and x and plug them in to get the coordinates that you need. After doing that, use the line that you've created and find a point that would fall directly above 75, or use the line of best fit (in a scatterplot, this is a line that fits most of the points).
Hope this helps!
