Answer:
D. There were no significant effects.
Step-by-step explanation:
The table below shows the representation of the significance level using the two-way between subjects ANOVA.
Source of Variation SS df MS F P-value
Factor A 10 1 10 0.21 0.660
Factor B 50 2 25 0.52 0.6235
A × B 40 2 20 0.42 0.6783
Error 240 5 48 - -
Total 340 10 - - -
From the table above , the SS(B) is determined as follows:
SS(B) = SS(Total)-SS(Error-(A×B)-A)
= 340-(240-40-10)
= 50
A researcher computes the following 2 x 3 between-subjects ANOVA;
k=2
n=3
N(total) = no of participants observed in each group =11
df for Factor A= (k-1)
=(2-1)
=1
df for Factor B = (n-1)
=(3-1)
=2
df for A × B
= 2 × 1
= 2
df factor for total
=(N-1)
=11-1
=10
MS = SS/df
Thus, from the table, the P-Value for all data is greater than 0.05, therefore we fail to reject H₀.
Vertex - The common endpoint of two rays at which an angle is formed.
Vertical Angles - Pairs of angles formed where two lines intersect.
The solution of the line x<5
Answer: d. .2474.
Step-by-step explanation:
Given : The cashier service time at the local branch of the Rivertown bank has an exponential distribution with a mean of 2.5 minutes.
The cumulative distribution function for exponential distribution is :-
, where
= Mean of the distribution.
The probability that the service time is between 2 and 4 minutes will be :
![P(2\leq X \leq 4)=P(X\leq4)-P(X\leq 2)\\\\= (1-e^{\frac{-4}{2.5}})-(1-e^{\frac{-2}{2.5}})\\\\=e^{\frac{-2}{2.5}}-e^{\frac{-4}{2.5}}\\\\=0.449328964117-0.201896517995\\\\=0.247432446123\approx0.2474](https://tex.z-dn.net/?f=P%282%5Cleq%20X%20%5Cleq%204%29%3DP%28X%5Cleq4%29-P%28X%5Cleq%202%29%5C%5C%5C%5C%3D%20%281-e%5E%7B%5Cfrac%7B-4%7D%7B2.5%7D%7D%29-%281-e%5E%7B%5Cfrac%7B-2%7D%7B2.5%7D%7D%29%5C%5C%5C%5C%3De%5E%7B%5Cfrac%7B-2%7D%7B2.5%7D%7D-e%5E%7B%5Cfrac%7B-4%7D%7B2.5%7D%7D%5C%5C%5C%5C%3D0.449328964117-0.201896517995%5C%5C%5C%5C%3D0.247432446123%5Capprox0.2474)
Hence, the correct option is d. .2474.
