If you meant
16=2ˣ then
remember
$y=a^x$ translates to $log_ay=x$

so
$16=2^x$ translates to $log_216=x$

A survey of 35 people was conducted to compare their self-reported height to their actual height. The difference between reporte

monitta

Answer:

The test statistic is t = 3.36.

Step-by-step explanation:

You're testing the claim that the mean difference is greater than 0.7.

At the null hypothesis, we test if it is 0.7 or less, that is:

$H_0: \mu \leq 0.7$

At the alternate hypothesis, we test if it is greater than 0.7, that is:

$H_1: \mu > 0.7$

The test statistic is:

$t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}$

In which X is the sample mean, $\mu$ is the value tested at the null hypothesis, s is the standard deviation and n is the size of the sample.

0.7 is tested at the null hypothesis:

This means that $\mu = 0.7$

Survey of 35 people. From the sample, the mean difference was 0.95, with a standard deviation of 0.44.

This means that $n = 35, X = 0.95, s = 0.44$

Calculate the test statistic

$t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}$

$t = \frac{0.95 - 0.7}{\frac{0.44}{\sqrt{35}}}$

$t = 3.36$

The test statistic is t = 3.36.

I am thinking of a number. If you multiply my number by four, add -4 to the product, and then take 1/3 of the sum, the result is

bogdanovich [222]

Answer:

$x = - \frac{7}{2}$

Step-by-step explanation:

x=unknown number

$\frac{4x + ( - 4)}{3} = - 6$

$4x - 4 = - 18$

$4x = - 14$

$x = \frac{ - 14}{4}$

simplify the fraction so... -7/2
