Answer:
Reject <em>H</em>₀ if: or .
Step-by-step explanation:
The hypothesis for the one-tail t-test is:
<em>H</em>₀: The population mean is 100, i.e. <em>μ</em> = 100.
<em>Hₐ</em>: The population mean is less than 100, i.e. <em>μ</em> < 100.
The significance level of the test is, <em>α</em> = 0.05.
The number of observations in the sample is, <em>n</em> = 25.
The degrees of freedom of the test is:
df = n - 1
= 25 - 1
= 24
Compute the critical value of <em>t</em> as follows:
*Use a <em>t</em>-table.
The rejection region can be defined as follows:
Reject <em>H</em>₀ if: or .
Answer:
no the numbers are repeating
Step-by-step explanation:
Answer:
Ans. the present value of $1,300/month, at 6.4% compounded monthly for 360 months (30 years) is $207,831.77
Step-by-step explanation:
Hi, first, we have to turn that 6.4% compound monthly rate into an effective rate, one that meets the units of the payment, in our case, effective monthly, that is:
Therefore, our effective monthly rate is 0.5333%, and clearly the time of the investment is 30 years*12months=360 months.
Now, we need to use the following formula.
Everything should look like this.
Therefore
Best of luck.
Answer:
x= 25/3 or 8.333333
Step-by-step explanation:
you add 11 to 10 to get 21
3x-4=21
add 4 to both sides, which will cancel out the (-4)
3x=25
divide each term by 3 to get x by itself
3x/3 = 25/3
you will then get x=25/3
