The explicit formula is B
For 645 and 738:
For these numbers we have that the difference between both is:
738 - 645 = 93
For 645 and 649:
For these numbers we have that the difference between both is:
649 - 645 = 4
Therefore, comparing the first two numbers of the second two numbers is different because the difference between the first two numbers is much larger.
Answer:
The difference between the first two numbers is much greater than the difference between the second two numbers.
Answer:
Die is not fair given that Pvalue< 0.05, hence we reject Null hypothesis
a) H0: Die = fair
b) Ha : Die ≠ fair
c) df = 5
Step-by-step explanation:
The expected frequency of every face values = 20
a) state Null hypothesis
H0: Die = fair
b) Alternate Hypothesis
Ha : Die ≠ fair
c) degree of freedom
df = ( n - 1 )
= ( 6 - 1 ) = 5
n = sample size ( number of faces a die has )
Note : After conducting hypothesis test
Pvalue ≈ 0.0026
test statistic ≈ 18.30
Hence we can conclude that die is not fair given that Pvalue < 0.05, hence we reject Null hypothesis
