Answer:

Therefore the required probability is $\frac{30}{351}$ .

Step-by-step explanation:

Two events are dependents event if the occurrence of one of them has effect on the probability of the other.

If A and B are dependents,

then,

P(AB)=P(A)P(B).

Given that,

There are 27 chocolates in a box.

Number of nuts chocolates = 4

Number of caramel chocolates = 8

Number of solid chocolates= 15.

The probability of that a solid candy is drawn is

$=\frac{\textrm{Number of solid chocolate}}{\textrm{Total number of chocolate}}$

$=\frac{15}{27}$ .

After selecting a solid chocolate, the number of chocolate is= (27-1)=26.

The probability that a nut candy is drawn is

$=\frac{\textrm{Number of nut chocolate}}{\textrm{Total number of chocolate}}$

$=\frac{4}{26}$

$=\frac{2}{13}$

Therefore the required probability is

$=\frac{15}{27}\times\frac{2}{13}$

$=\frac{30}{351}$

Calculate the upper and lower limit for a 95% confidence interval about this mean. a family needs a new car, but isn't sure they

Ket [755]

<span>Answer: Where:
θ = confidence value
n = number of observations
μ = mean
Θ = standard deviation
... then your interval will be:
μ - θΘ/√n ≤ X ≤ μ - θΘ/√n
For some reason they want you to calculate the standard error, which is the Θ/√n section, and I mentioned the 1.96 value, so the above equation simplifies to: μ - 1.96SE ≤ X ≤ μ - 1.96SE</span>
