You obtain a dataset from a random sample. • You double-checked your dataset, and there were no typos, and no errors. • All cond

itions were met to develop a confidence interval. • You develop a 97% confidence interval for the population mean µ, and your confidence interval is 74.3 < µ < 78.3. • You double-checked your calculations, and everything was done correctly. Question: Later, you find out that the actual population mean is µ = 71. Why doesn’t your confidence interval contain the actual population mean?

Answer:

Interval is given with 97% confidence. Thus there is 3% probability that interval is not true.

Step-by-step explanation:

In Statistics, estimated intervals are given with some confidence level. In this example person develop the interval with 97% confidence.

<em>Statistically</em>, this means that the person can be 97% sure (not 100%)  that population mean is 74.3 < µ < 78.3. There is still 3% probability that population mean falls outside of the interval.

Small sample size may also lead wrong estimates.

2. y=2x+3 

When x =0 and y= something, the 'something' is your y-intercept which is b in the y=mx+b formula.  Then we look at what is changed in the x and y value to determine the m part.  the x increase by 1 and y increase by 2 so the m part is 2. 

3. y=-7x 
Same as the last one, there is no y-inter this time because the y=0 when x=0/  So the y deceased by 7 each time and x incease by 1 so it is -7 for the m part.

The sum of a number times 8 and 21 is less than -16.
vodka [1.7K]

Hello.

First of all, let the number be t.

8 times t can be written like this:

\mathrm{8t}

Notice that the number is before the variable and the times sign (×) is not there.

We can write it as 8×t, but we usually write it as 8t.

The sum of means we add:

8t+21

Now, "less than" is "<" :

\mathrm{8t+21 < -16}

Therefore, the answer is

\mathrm{8t+21 < -16}

I hope it helps.

Have a nice day.
