(Small sample confidence intervals for a population mean) suppose you are taking a sampling of 15 measurements. you find that x=

Luda [366]

Answer:

The 99% confidence interval is $71.67 < \mu < 78.33$

Step-by-step explanation:

From the question we are told that

The sample size is $n = 15$

The sample mean is $\= x = 75$

The standard deviation is $s = 5$

Given that confidence is 99% then the level of significance is mathematically represented as

$\alpha = 100 - 99$

$\alpha = 1\%$

$\alpha = 0.01$

Next we obtain the critical values of $\frac{ \alpha }{2}$ from the normal distribution table

The value is

$Z_{\frac{ \alpha }{2} } = 2.58$

Generally the margin for error is mathematically represented as

$E = Z_{\frac{ \alpha }{2} } * \frac{ s}{ \sqrt{n} }$

=> $E = 2.58 * \frac{ 5}{ \sqrt{15} }$

=> $E = 3.3307$

The 99% confidence interval is mathematically represented as

$\= x -E < \mu < \= x +E$

=> $75 - 3.3307 < \mu$

=> $71.67 < \mu < 78.33$

Rom4ik [11]

Answer:

-5k+7p+1 I THINK

Step-by-step explanation

destribute the negative

(-3k + p – 1) – (2k – 6p – 2)

-2k+6p+2

add to the (-3k + p – 1) to simplify

-5k+7p+1

galben [10]

You did the top right but the denominator is 0 so the slope in undefined or 0.

Hope this helps!

For the right triangle find the missing length. Round your answer to the nearest tenth.

Brut [27]

Answer:

3.5

Step-by-step explanation:

tan60 = w/2

Multiply 2 on both sides to get the w by itself.

tan60 x 2 = w

Put tan60 into the calculator.

2 x 1.732050808 = w

Multiply.

w = 3.5
