Answer with explanation:
Mean of seven Distinct random Samples are : →23.2, 26.7,24.9,24.6,28.0, 26.3, 23.4.
Mean of Population is equal to Mean of seven Distinct random Samples of Population.
⇒The Value which is the best estimate of the mean of the population is:
Option B:→ 24.2

Answer:
weight = 5, 6.5, 7.2, 9, 16
cost = $2.50, $3.25, $3.60, $4.50, $8.00
Step-by-step explanation:
The first column tells you the cost is ...
$2.50/(5 lb) = 0.50 $/lb
That is, each bottom number is half the top number, or each top number is double the bottom number.
The table is ...
weight = 5, 6.5, 7.2, 9, 16
cost = $2.50, $3.25, $3.60, $4.50, $8.00
Answer:
- 1/243 ≈ 0.004 (which is a low probability)
Explanation:
The event landing on a three or four on a rolling is independent of the event of landing on a three or four on any other rolling.
Thus, for independent events you calculate the joint probability as the product of the probabilities of each event:
- P(A and B and C and D and E) = P(A) × P(B) × P(C) × P(D) × P(E)
Here, P(A) = P(B) = P(C) = P(D) = P(E) = probability of landing on a three or four.
Now to calculate the probability of landing on a three or four, you follow this reasoning:
- Positive outcomes = three or four
- Number of positive outcomes = 2
- Possible outcomes = one, two, three, four, five, or six
- Number of possible outcomes = 6
- Probability = numer of positive outcomes / numer of possible outcomes
Finally, probability of landing on a three or four on all five rolls: (1/3)⁵ = 1/243 ≈ 0.004 ← answer
