Answer:
Step-by-step explanation:
From the information given,
The null hypothesis is
H0:p = 0.40 H0:p = 0.40
The alternative hypothesis
Ha:p < 0.40 Ha:p < 0.40.
The p value of 0.033
The decision rule states that
If the significance level, α < the p value, we would accept the null hypothesis.
If the significance level, α > the p value, we would reject the null hypothesis.
From the given options,
D) At the significance level α=0.05, the null hypothesis is rejected. There is convincing evidence to support the claim that fewer than 40% of the students at the local university read at least one book last year.
Answer:
the first graph is the answer
Step-by-step explanation:
A!!!
All the tax comes out of $235 So it would be 6.2% from 235 3% from 235 And 1% from 235 So if you at all the percents together You get 10.2% Which is 23.97 In tax plus the 36 Minus off of the 235 It makes net pay 175.03
0.21 would be rational,because it is a terminating decimal,which means that it has an ending point and can be converted into a fraction.ur welcome
Answer:
u= -8/17 [-8, ∞)
Step-by-step explanation:
solve it like regular equation
17u≥-8
divide 17 on both side
then you get u≥-8/17
so, (u) is any value greater than or equal to -8/17
less than equal means solid dot on number line i think its called also mean ([) meaning it includes this value too. It is a multiplication so it can be any number above -8 or -8 itself. Thus, the interval notation will be [-8, ∞). Infinite is not a fix number so we use this (). hope this helps good luck
