Answer:

Approx. 14.16

Step-by-step explanation:

First note that sqrt(196) = 14 and that the next higher perfect square is 225, whose sqrt is 15. Thus,

sqrt(201) is in between 14 and 15.

You could use an approach called "extrapolation" to approximate the root of 201:

The difference between 225 and 196 is 31; the difference between 201 and 196 is 5. So, form the proportion (5/31) and add this to 14:

Approx. root of 201 is 14 + (5/31), approximately, or 14.16.

Note that sqrt(201) done on the calculator is 14.18, which is better than 14.16, but these two results are nevertheless quite close.

Answer:

p-value = 0.1277

Step-by-step explanation:

p-value is the probability value tell us how likely it is to get a result like this if the Null Hypothesis is true.

Firstly we find the mean and standard deviation of the given data set.

⇒ Mean = $\frac{4.41 +4.37+ 4.33+ 4.35 +4.30 +4.39 +4.36+ 4.38+ 4.40+ 4.39}{10}$

⇒ Mean = 4.368

$Standard deviation(\sigma) = \sqrt{\frac{1}{n}\sum_{i=1}^{n}{(x_{i}-\bar{x})^{2}} }$

where, $\bar{x}$ is mean of the distribution.

⇒ Standard Deviation = 0.034

Applying t- test:

Let out hypothesis is:

H₀: μ = 4.35

H₁: μ ≠ 4.35

Now,

Here, μ = Population Mean = 4.35

$\bar{x}$ = Sample Mean = 4.368

σ = Standard Deviation = 0.034

n = 10

$t=\frac{\bar{x}-\mu}{\frac{\sigma}{\sqrt{n}} }$

Putting all values we get, t = 1.6777 with (10 -1) = 9 degree of freedom.

Then the p-value at 99% level of significance.

⇒ p-value = 0.1277
