10kg's is greater than 18,000
18,000 < 10kg
Answer:
Point estimate: 0.391
Margin of error: 0.042
Step-by-step explanation:
A confidence interval has two bounds, a lower bound and an upper bound.
A confidence interval is symmetric, which means that the point estimate used is the mid point between these two bounds, that is, the mean of the two bounds.
The margin of error is the absolute difference between these bounds and the point estimate.
In this question:
Lower bound: 0.349
Upper bound: 0.433
Point estimate: (0.349 + 0.433)/2 = 0.391
Margin of error: |0.349 - 0.391| = |0.433 - 0.391| = 0.042
Answer:
The probability of rolling a number less than 6 on 1 roll of a die is
= 0.833is
Step-by-step explanation:
Let
S be the sample space for a rolling of a Die
∴ is total number of outcomes for a rolling of a die are ={ one, two, three, four, five, six} six
i.e { 1,2,3,4,5,6}
∴ n (S) = 6
let A be the event of getting a number less than six
then the possible outcomes are { 1, 2, 3, 4, 5 }
∴ n(A) = 5
To Find:
P (A) = ?
Solution:
we know that probability is given by
