A square has a perimeter of 52 meters. What is the length of each side?
rjkz [21]

Hey there! :D


A square has four sides.


The perimeter of something is all the sides added up.


So, we know that it would be 52 divided by 4.


52/4= 13


Each side is 13 meters long.


I hope this helps!

Perform a one-proportion z-test for a population proportion. Be sure to state the hypotheses and the P-Value. State your conclus
emmainna [20.7K]

Answer:

There is not enough statistical evidence in the sample taken by the veterinarian to support his skepticism

Step-by-step explanation:

To solve this problem, we run a hypothesis test about the population proportion.

Proportion in the null hypothesis \pi_0 = 0.37

Sample size n = 150

Sample proportion p = 54/150 = 0.36

Significance level \alpha = 0.05

H_0: \pi_0 = 0.36\\H_a: \pi_0

Test statistic = \frac{(p - \pi_0)\sqrt{n}}{\sqrt{\pi_0(1-\pi_0)}}

Left critical Z value (for 0.01) Z_{\alpha/2}= -1.64485

Calculated statistic = = \frac{(0.36 - 0.37)\sqrt{150}}{\sqrt{0.37(0.63)}} = -0.254

p-value = 0.6003

Since, test statistic is greater than critical Z, the null hypothesis cannot be rejected. There is not enough statistical evidence to state that the true proportion of pet owners who talk on the phone with their pets is less than 37%. The p - value is 0.79860.
