Answer:

The probability of selecting 5 both times is 0.002.

Step-by-step explanation:

We are given that you randomly select an integer from 0 to 19 (inclusively) and then randomly select an integer from 0 to 24 (inclusively).

And we have to find the probability of selecting 5 both times.

As we know that the probability of an event is given by;

Probability = $\frac{\text{Favorable number of outcomes}}{\text{Total number of outcomes}}$

Now, here between integer from 0 to 19 (inclusively);

Number of times 5 comes = 1

Total number of integers = 20

Similarly, between integer from 0 to 24 (inclusively);

Number of times 5 comes = 1

Total number of integers = 25

So, the required probability = $\frac{1}{20}\times \frac{1}{25}$

= $\frac{1}{500}$ = 0.002

Hence, the probability of selecting 5 both times is 0.002.

Answer:

$t_{\alpha/2} = t_{0.05/2} = t_{0.025} = 2.0322$

Step-by-step explanation:

We have a sample of size n = 35, $\bar{x} = 92$ and $s = 5$ . As we want to construct a 95% confidence interval to estimate the value of the true population mean $\mu$ , we should use the pivotal quantity given by $T = \frac{\bar{X}-\mu}{S/\sqrt{n}}$ which comes from the t distribution with n - 1 = 35 - 1 = 34 degrees of freedom. Besides we should use the t-value $t_{\alpha/2} = t_{0.05/2} = t_{0.025} = 2.0322$ , i.e., regarding the t-distribution with 34 degrees of freedom, we have an area of 0.025 above 2.0322 and below the probability density function. The rationale behind this is that $P(-2.0322\leq T\leq 2.0322) = 0.95$ because of the simmetry of the t distribution.

What conditions must hold for a probability distribution to be acceptable?

VashaNatasha [74]

A distribution of probabilities is a numerical means of describing all unique combinations and the probabilities for a provided random variable, and the further discussion can be defined as follows:

The distributions mean (average), basic difference, skewness, as well as courtesies, are among such factors.
A formula, table, or chart can show a probability distribution for discrete probability distribution X that providing $\bold{p(x) = P(X=x)}$ for all x.
For just a discrete random variable, the probability assigns annual probabilities with only a countless multitude of unique x values.
<em><u>Each result is likely to be between 0 and 1, including.</u></em>

Therefore, the final choice is "Option A".
