Answer: a) z=1.43
b) 0.1528
Step-by-step explanation:
The given set of hypothesis :


Since the alternative hypothesis
is two-tailed , so we perform two-tailed test.
Also, it is given that : A random sample of n=76 Americans found 28 with brown eyes.
Sample proportion: 
a) The z-statistic would be :-


b) P-value for two-tailed test = 2P(Z>|z|)= 2P(z>|-1.43|)
=2P(z>1.43)
=2(1-P(z≤1.43)
=2-2P(z≤1.43)
= 2-2(0.9236)[Using standard z-table]
= 2-1.8472=0.1528
Hence, the P-value of the test= 0.1528
Answer:
6 times whatever x is would be greater that -54
Answer:
x=28+n
Step-by-step explanation:
So, the teacher is giving Jonathan papers so we know its addition.
28+n
So lets have x equal the amount of papers he has on his desk after the new papers are added.
x=28+n
Answer:
It should be 5.99x+4, where x is the number of pizzas ordered.
The answer is 2268pi ft^3
