Lucy is using a one-sample t ‑test based on a simple random sample of size n = 22 to test the null hypothesis H 0 : μ = 16.000 c

slega [8]

Answer:

The value of test statistic is 1.338

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 16.000

Sample mean, $\bar{x}$ = 16.218

Sample size, n = 22

Alpha, α = 0.05

Sample standard deviation, s = 0.764

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 16.000\text{ cm}\\H_A: \mu < 16.000\text{ cm}$

We use one-tailed t test to perform this hypothesis.

Formula:

$t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }$

Putting all the values, we have

$t_{stat} = \displaystyle\frac{16.218 - 16.000}{\frac{0.764}{\sqrt{22}} } = 1.338$

Thus, the value of test statistic is 1.338

8). CA = 9.20 ( multiply the given decimal by 100)

AB = 10.80

CB = 8.50

9). option e is correct side - side - side

10). SSS

11). 1 ( because with the given info. u can calculate the perimeter of the traingle only )

12) through the given info we can only find the perimeter of the traingle

so,

perimeter = sum of all sides

→ 9.2 + 8.5 + 10.8 = 28.5 m

hope this answer helps you dear...take care may u have a great day ahead!
