Which of the following shows these numbers in order from least to greatest?

koban [17]

9514 1404 393

Answer:

$\sqrt[3]{2197}, 14\frac{1}{3}, 13\frac{12}{8}, \sqrt{213.16}, 15, 2^4$

Step-by-step explanation:

The values of the given numbers, in order, rounded to 1 decimal place are ...

$\begin{array}{cc}\sqrt{213.16}&14.6\\14\frac{1}{3}&14.3\\15&15.0\\13\frac{12}{8}&14.5\\2^4&16.0\\\sqrt[3]{2197}&13.0\end{array}$

Their least-to-greatest ordering is shown above.

Anika [276]

Answer:

Value of test statistics = 2.30

Step-by-step explanation:

We are given that for a sample of 35 items from a population for which the standard deviation is 20.5, the sample mean is 458.

Also, Null Hypothesis, $H_0$ : $\mu$ = 450

Alternate Hypothesis, $H_1$ : $\mu\neq$ 450

The test statistics that will be used here is One sample t-test statistics;

T.S. = $\frac{\bar X-\mu}{\frac{s}{\sqrt{n} } }$ ~ $t_n_-_1$

where, $\bar X$ = sample mean = 458

s = sample standard deviation = 20.5

n = sample of items = 35

So, test statistics = $\frac{458-450}{\frac{20.5}{\sqrt{35} } }$ ~ $t_3_4$

= 2.30

Therefore, the value of test statistics is 2.30 .
