If A denotes some event, what does Upper A overbar denote? If P(A)equals0.999, what is the value of P(Upper A overbar)? Wh

meriva

Answer:

<h3>The event $P(\overline{A})$ denotes the complement of event A.</h3><h3>The value of $P(\overline{A})$ is 0.001</h3>

Step-by-step explanation:

Given that A denotes some event .

And also given that P(A)=0.999

<h3>To find the value of $P(\overline{A})$ :</h3>

Here the event $P(\overline{A})$ denotes the complement of event A Therefore $P(\overline{A})$ contains all the events that does not occur in A.

We know that the total probability is 1

So we have that

$P(A)+P(\overline{A})=1$

$P(\overline{A})=1 -P(A)$

$=1-0.999$

$=0.001$

Hence the complement of event A is $P(\overline{A})=0.001$

<h3>Therefore the value is $P(\overline{A})=0.001$ </h3>

The essay lengths of 29 randomly sampled essays are used to estimate the mean of the population. What t-score should be used to

slavikrds [6]

Answer:

A t-score of 1.701 should be used to find the 95% confidence interval for the population mean

Step-by-step explanation:

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 29 - 1 = 28

Now, we have to find a value of T, which is found looking at the t table, with 28 degrees of freedom(y-axis) and a confidence level of 0.95( $t_{95}$ ). So we have T = 1.701.
