If Body temperatures of healthy adults have a bell-shaped distribution with a mean of 98.20°F anda standard deviation of 0.93°F.

lisov135 [29]

Step 1

Given; If Body temperatures of healthy adults have a bell-shaped distribution with a mean of 98.20°F and a standard deviation of 0.93°F.

Using the empirical rule, what is the approximate percentage of healthy adults with body temperatures between 96.34°F and 100.06°F?

Step 2

$P(96.34The empirical rule states that 95% of the data fall within two standard deviations of the mean. Thus, 95% of healthy individuals have body temperatures between 96.34F and 100.06F.Answer;[tex]95\text{\%}$

Solve for x in this inequality. Show all your work and graph your solution. 4(x-3)<2x-4

maw [93]

Answer:

x<4

Step-by-step explanation:

To solve for x in the inequality equation, the terms should be rearranged such that x is on one side and integers are on the other side.

First, expand 4(x-3).

This will obtain:

$4x - 12 < 2x - 4$

Now, shift x terms and integers on each side.

$4x - 2x < - 4 + 12$

After simplifying, it will get:

$2x < 8$

Finally, we can solve for x.

$x < 4$

We can also draw the respective graph (please don't mind my drawings), where the area shaded in green is the range.

It is known that the population variance is 144. At 95% confidence, what sample size?a. 22.b. 23.c. 24.d. 25.e. none of the abov

romanna [79]

Answer:

(E) None of the above

Step-by-step explanation:

The statistic provided is that of the population but the statistic you seek is that of the sample.

Looking at the statistic itself, Variance is the square of Standard Deviation or standard deviation is the square root of variance.

Hence you calculate the standard deviation of the population mean:

√144 = 12

The population standard deviation of/from the mean value is 12.

It could be possible to decipher the sample mean from population mean but not sample size.

So, you can't pick just any answer. Population size should be given first.
