If a random sample of size nequals=6 is taken from a population, what is required in order to say that the sampling distributio

goldenfox [79]

Answer:

$\bar X \sim N(\mu , \frac{\sigma}{\sqrt{n}})$

In order to satisfy this distribution we need that each observation on this case comes from a normal distribution, because since the sample size is not large enough we can't apply the central limit theorem.

Step-by-step explanation:

For this case we have that the sample size is n =6

The sample man is defined as :

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

And we want a normal distribution for the sample mean

$\bar X \sim N(\mu , \frac{\sigma}{\sqrt{n}})$

In order to satisfy this distribution we need that each observation on this case comes from a normal distribution, because since the sample size is not large enough we can't apply the central limit theorem.

So for this case we need to satisfy the following condition:

$X_i \sim N(\mu , \sigma), i=1,2,...,n$

Because if we find the parameters we got:

$E(\bar X) =\frac{1}{n} \sum_{i=1}^n E(X_i) = \frac{n\mu}{n}=\mu$

$Var(\bar X)= \frac{1}{n^2} \sum_{i=1}^n Var(X_i) = \frac{n\sigma^2}{n^2}= \frac{\sigma^2}{n}$

And the deviation would be:

$Sd (\bar X) = \frac{\sigma}{\sqrt{n}}$

And we satisfy the condition:

$\bar X \sim N(\mu , \frac{\sigma}{\sqrt{n}})$

PLEASE HELP ME

Mila [183]

Answer:

(i)

time to bounce in one direction is 0.75 sec

(ii)

time to bounce in other direction is 1.5 sec

(iii)

total time is 2.25 sec

Step-by-step explanation:

Time to bounce in one direction:

we can see that height is increasing till t=0.75sec

so, time to bounce in one direction is 0.75 sec

Time to bound in other direction:

we can see that height is decreasing from t=0.75 to 2=2.25 sec

so, time to bounce in other direction is 2.25-0.75

=1.5 sec

Total time :

We know that

total time = (time to bounce in one direction)+(time to bounce in other direction)

now, we can plug values

total time =0.75+1.5=2.25 sec
