Answer:
Null hypothesis:
Alternative hypothesis:
And the best answer for this case is:
C. p-value
Step-by-step explanation:
Data given and notation
n represent the random sample taken
estimated proportion of interest
is the value that we want to test
represent the significance level
z would represent the statistic (variable of interest)
represent the p value (variable of interest)
Concepts and formulas to use
We need to conduct a hypothesis in order to test the claim that the true proportion i 0.72 or no.:
Null hypothesis:
Alternative hypothesis:
When we conduct a proportion test we need to use the z statistic, and the is given by:
(1)
The One-Sample Proportion Test is used to assess whether a population proportion is significantly different from a hypothesized value .
For this case the only probability that can be calculated from the statistic calculated is the p value given by:
And the best answer for this case is:
C. p-value
Answer:
830 cents
5n + p
Step-by-step explanation:
Given that :
Number of nickels = 140
Number of pennies = 130
Total coins :
140 nickels + 130 pennies
1 nickel = 5 cent
1 penny = 1 cent
Hence,
140(5) + 130(1)
700 + 130
= 830 cents in total
If :
number of nickels = n
Number of pennies = p
Tot coins :
5n + 1p
5n + p
