Answer:
Null hypothesis (
): The birth weight of the first born of identical twins is the same as the birth weight of the second born.
Alternative hypothesis (
): The birth weight of the first born of identical twins is higher than the second born.
Step-by-step explanation:
Please note that the null hypothesis is the hypothesis we always want to reject or prove to be false. Hence in this study, the objective of the study is clearly stated that the researcher want to determine whether the twin born first tends to weigh more than the twin born second.
Therefore, the null hypothesis we assume that the weight of the identical twins is the same regardless of who come first or last., while the alternative hypothesis is constructed or stated to answer the research objective.
C = 2 * pi * r....for r
divide both sides by 2 * pi
C / (2(pi)) = r
Answer:
Option (a)
Step-by-step explanation:
The given equation is
y = 4 (2ˣ)
To find y-intercept, substitute x=0 in the equation.
y = 4 (2⁰) = 4 (1) =4
Hence y-intercept is 4.
Since y-intercept is 4, the equation should pass through the point (0,4).
The only graph passing through the point (0,4) is the graph in option (a).
Hence the answer is option (a).
Hello!
The mean is 12
The data has a standard deviation of 4
Look and see how far away 18 is from 12 using 4
12 + 4 = 16
16 is one deviation
16 + 4 = 20
20 is two deviation
18 is right in the middle
The answer is C. 1.5 deviations
Hope this helps!
The ball seems to be traveling at its greatest average speed between x = 4 and x = 6 because the graph between 4 and 6 is a straight line, meaning the ball has reached the greatest possible speed.
