What you would do is divide -50 by -10 and turn it into a positive, and remember what you do to one side you have to do to the other

Refer to the technology output given to the right that results from measured hemoglobin levels (g/dL) in 100 randomly selected a

charle [14.2K]

Answer:

Step-by-step explanation:

a)

Confidence interval in less than symbol expressed as

$\bar{x} - E < \mu < \bar{x} + E
$

Where $\bar{x}$ is sample mean and $E$ is margin of error.

$13.03 < \mu 13.42
$

b)

The given t interval is $(13.032 , 13.418 )
$

That is $\bar{x} - E = 13.032$ and $\bar{x} + E = 13.418$

Solve these two equation by adding together.

$2 \bar{x} = 13.032 + 13.418
\\\\\bar{x} = 13.225$

Solve this value of \bar{x} in equation $\bar{x} - E = 13.032$ and solve for $E$

$13.225 - E = 13.032
\\\\E = 0.193
$

Best point estimate of $\mu = \bar{x} = 13.225
$

Best point estimate of margin of error = 0.193

c)

Since sample size = 100 which is sufficiently large (Greater than 30) , it is no need to confirm that

sample data appear to be form a population with normal distribution.

If the sphere shown above has a radius of 14 units then what is the approximate volume of the sphere

oksano4ka [1.4K]

Answer:

About 11494.04

Step-by-step explanation:

There is no sphere shown above but I can still get you the answer:

The formula for the volume of a sphere is $\frac{4}{3} *$ π*r³

Putting in the radius, we get:

$\frac{4}{3}$ *π*14³=

$\frac{4}{3}$ *π*2744=

$\frac{10976}{3}$ *π=

3658.66*π≈11494.04
