Answer:
0.456
0.324
Explanation:
The null and alternative hypothesis :
H0 : p = 0.40; HA :p < 0.40
Test statistic :
(Ph - P) / sqrt[(p*(1-p))/n]
Ph = X / n
X = 34 ; n = sample size = 80
Ph = 34 / 80 = 0.425
(0.425 - 0.4) / sqrt[(0.4(0.6)) / 80]
0.025 / sqrt(0.003)
0.025 / 0.0547722
Test statistic = 0.4564359
Test statistic = 0.456
Using the P-value from Zscore calculator :
Significance level of 95% ; one tailed
Z statistic value = 0.456
P value = 0.324195
= 0.324 ( 3 decimal places)
Answer:
There are 5 numbers
Explanation:
First, the number must be a whole number and divisible by 4.
20^2 is 400.
And there are 4, 8, 12, 16 ,20; 5 number divisible by 4.
23^2 is already 529.
The next number divisible by 4 is 24 which is over 500.
So there are 5 numbers. They are 16, 64, 144, 256, 400.
