How can I Estimate the mean length. How can I select the modal class ?
1 answer:
Answer:
To estimate the mean length.
From the table lengths and its corresponding frequency are given
we know that,
The mean formula is defined as the sum of the observations divided by the total number of observations.
The formula to calculate the mean of grouped data. The formula is,
we get, Midpoint of the intervals are,
0.95, 2.95, 4.95, 6.95, 8.95, 10.95
Mean is,
we get,
Answer is: 6.034

Answer:
Step-by-step explanation:
From Bayes' theorem is stated mathematically as the following equation:[2]
{\displaystyle P(A\mid B)={\frac {P(B\mid A)\,P(A)}{P(B)}},}
where A and B are events and P(B) ≠ 0.
P(A) and P(B) are the probabilities of observing A and B without regard to each other.
P(A | B), a conditional probability, is the probability of observing event A given that B is true.
P(B | A) is the probability of observing event B given that A is true.
At this point, go through the attached file before you continue with part B.
Part B)
P(silver) = P(silver from SS)+P(silver from GS)
note P(SS)=P(GG)=P(GS) = 1/3
P(silver from SS) = 1
P(silver from GS) = 1/2
hence
P(Silver from SS) = 1/3
P(Silver from GS) = 1/3 *1/2
P(Silver) = 1/3*1+1/3*1/2
required probability = P(Silver from SS)/P(Silver) = 2/3
