Answer: 0.0708
Step-by-step explanation:
Let μ denote the true average reaction time to a certain stimulus.
To determine : The P-value for a z test of H0: μ = 5 versus Ha: μ > 5.
In the given set of hypothesis , the alternative hypothesis is right -tailed , so the test is a right tailed test .
Given test statistic : a) z= 1.47
Now, the p-value for the right tailed test :
![P(z>1.47)=1-P(z\leq1.47)\ \ [\because P(Z>z)=1-P(Z\leq z)]](https://tex.z-dn.net/?f=P%28z%3E1.47%29%3D1-P%28z%5Cleq1.47%29%5C%20%5C%20%5B%5Cbecause%20P%28Z%3Ez%29%3D1-P%28Z%5Cleq%20z%29%5D)
[Using the p-value table for z]
Hence, the required P-value = 0.0708
Answer:
36
Step-by-step explanation:
5:4 ratio 45/5 is 9 so 9 x 4 =36
Inequalities are number sentences that compare two numbers. sometimes we use variables when writing inequality’s.
Answer: 32
Step-by-step explanation:
4 cubed 2 divided by 4
Simply is
4 to the power 3 multiplied by 2 divided by 4
4*4*4*2/4
128/4= 32
2a^2b^3(4a^2+3ab^2-ab)=?
<span>
is what I presume you actually meant. </span>
<span>
Pull out the common factors of (4a^2+3ab^2-ab) and you will get </span>
<span>
a(4a+3b^2 -b) </span>
Substitute this back into the original equation and you get
<span>
2a^2b^3[a(4a+3b^2-b)] = </span>
2a^3b^3(4a+3b^2-b) =
<span>2a^3b^3(4a-b+3b^2)
</span>
