Answer:

Symmetric

Step-by-step explanation:

The data is spread out symmetrically. It isn't uniform because the values aren't around each others values. It isn't skewed because the data isn't 'closer' to one side.

Answer: z= 1.51

Step-by-step explanation:

Test statistic for proportion is given by :-

$z=\dfrac{p-P}{\sqrt{\dfrac{PQ}{n}}}$

Where n is sample size ,p is the sample proportion , P Is the population proportion and Q =1 - P.

Given : P=57% = 0.57

Q= 1- P = 1-0.57=0.43

n = 25

$p=\dfrac{18}{25}=0.72$

Test statistic for proportion will be :-

$z=\dfrac{0.72-0.57}{\sqrt{\dfrac{0.57\times0.43}{25}}}\approx1.51$

We should report the value of test statistic z= 1.51
