In constructing 98% confidence intervals for means, it is true that the statistic is good enough, and is less uncertain.

<h3>What is a confidence interval?</h3>

A confidence interval expresses the degree of uncertainty surrounding a given statistic. A margin of error is frequently used with confidence intervals. It reveals the degree to which you may be certain that the findings of a poll or survey correspond to what you would anticipate discovering if it were possible to poll the complete population. Levels of confidence are inextricably linked to confidence intervals.

Your level of confidence in your findings is shown by the confidence interval. You can never be certain that your results will hold for future surveys or experiments. In statistics, being 95% or 98.5% certain is typically seen as "good enough."

A tank containing 2.85 cube of oil how many bottles of 300 ml capacity can be filled out of it​
Ronch [10]

Answer:

9,500 bottles.

Step-by-step explanation:

1 cubic meter = 1000000 milli liters

We can convert (2.85 cubic meter) to (milli liters) as

1 cubic meter = 1000000 milli liters

2.85 cubic meter = X milli liters

If we Cross multiply and find X, we have

X milli liters = [(2.85 cubic meter × 1000000 milli liters) ] / 1 cubic meter

X= 2850,000 milli liters

Then (2.85 cubic meter) will be equal to ( 2850,000 milli liters)

Capacity of the Bottle = 300 ml

Number of bottles that 300 ml capacity can be filled out of it =

(2850,000 milli liters) / (300 ml)

= 9,500 bottles.

HELP ME!! SOMEBODY PLEASE HELP ME
IRISSAK [1]
6^2 = x (x - 9)
x^2 - 9x - 36 = 0
(x -12)(x + 3) = 0
x - 12 = 0; x = 12
x +3 = 0; x = -3

so in this case x = 12 then DC = 12 - 9 = 3

y^2 = 12^2 - 6^2
y^2 = 144 - 36
y^2 = 108
y = 10.4

Find the slope of the line passing through the points (8,-3) and (4,-1)
docker41 [41]

\rm \to m =  \dfrac{y_2 - y_1}{x_2 - x_1}

\\  \\

\rm \to m =  \dfrac{ - 1 - 3}{4 - 8}

\\  \\

\rm \to m =  \dfrac{ - 4}{4 - 8}

\\  \\

\rm \to m =  \dfrac{ - 4}{ - 4}

\\  \\

\rm \to m = \cancel  \dfrac{ - 4}{ - 4}

\\  \\

\rm \to m = 1
