Answer:
(22.74,24.06) is the required 95% confidence interval for the population mean ACT score of University of Oklahoma students.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 121
Sample mean = 23.4
Sample standard deviation = 3.65
Level of significance = 0.05
Degree of freedom

95% Confidence interval:
Calculation of critical value:
Putting the values, we get,
(22.74,24.06) is the required 95% confidence interval for the population mean ACT score of University of Oklahoma students.
Slope is rise/run
to find it we do (y1-y2)/(x1-x2)
y1 means the 1st y and y2 means the second y
in (x,y) form
y1=4
y2=4
x1=10
x2=7
(4-4)/(10-7)=0/3=0
slope is 0
Answer:
a₅=27.
Step-by-step explanation:
1) according to the condition the given subsequence is arithmetic sequence. It means, the a₁=7 and d=5, then
2) a₅=a₁+4*d; => a₅=7+4*5=27.
Yes it can and the answer would be 0.5
Terminating decimals are numbers that never stop going after the period. Such an example would be 10/3 which would give 3.333333 indefinitely. 1/2 gives a whole number, that is, 0.5
Answer:
<h3>RO = 107.36</h3>
<u>Step</u>-<u>by</u>-<u>step</u> <u>explanation</u>:
ΔLMN = ΔOPR ----- (<em>given</em>)
<h3>so,-----------------------</h3>
NM / NL = RP / RO
19 / 34 = 60 / RO
RO = 60 × 34 ÷ 19
RO = 107.36
