Answer:
a
The null hypothesis is
The alternative hypothesis is
b
c
d
There no sufficient evidence to conclude that 75% of adults say that it is morally wrong to not report all income on tax returns
Step-by-step explanation:
From the question we are told that
The sample size is
The number that said it is morally wrong is
The level of significance is
The population proportion is
Generally the sample proportion is mathematically represented as
=>
=>
The null hypothesis is
The alternative hypothesis is
The standard error is mathematically represented as
=>
=>
Generally the test statistics is mathematically represented as
=>
=>
Generally the p-value is mathematically represented as
From the the z-table
=>
=>
From the calculation
Hence we fail to reject the null hypothesis
Thus there no sufficient evidence to conclude that 75% of adults say that it is morally wrong to not report all income on tax returns
Answer:
0 and -3
Step-by-step explanation:
Natural numbers are all whole numbers from 1 to infinity. i.e
1, 2, 3, 4 . . .
These numbers do not include 0.
Integers are all whole numbers (positive and negative) including 0. i.e
. . ., -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, . . .
These numbers are all natural numbers including their negative counterparts (i.e negatives of the natural numbers) and also 0.
<em>So from the options in the question:</em>
1 is a natural number as well as an integer
-5.41 is not a natural number neither is it an integer.
3 root 12 (written as ) is neither a natural nor an integer number.
0 is an integer but not a natural number
-3 is an integer but not a natural number
-9/7 is neither a natural nor an integer number.
23 is a natural number as well as an integer
Therefore, 0 and -3 are integers but not natural numbers
