Answer:
Now we can calculate the p value with this probability:
If we use a significance level os 0.05 we see that the p value is lower than the significance level so then we can conclude that the true proportion of students with jobs is higher than 0.35 for this case. If we decrease the significance level to 1% the result changes otherwise not.
Step-by-step explanation:
Information given
n=78 represent the random sample taken
X=36 represent the students with jobs
estimated proportion of students with jobs
is the value that we want to test
z would represent the statistic
represent the p value
Hypothesis to test
We want to test if the proportion of students with jobs is higher than 0.35, the system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing the info we got:
Now we can calculate the p value with this probability:
If we use a significance level os 0.05 we see that the p value is lower than the significance level so then we can conclude that the true proportion of students with jobs is higher than 0.35 for this case. If we decrease the significance level to 1% the result changes otherwise not.
The probability of not spinning an even number should be two out of three or 2/3. because there is only 1 even number (2).
The expected value of the discrete distribution is of 20.97, hence option C gives the correct answer.
<h3>What is the mean of a discrete distribution?</h3>
The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability.</u>
Hence, according to the table, the expected value is given by:
E(X) = 12 x 0.08 + 18 x 0.15 + 20 x 0.31 + 22 x 0.08 + 24 x 0.15 + 25 x 0.23 = 20.97.

Step-by-step explanation:

Formula of area of a parallelogram is :
- Area of parallelogram = b × h
○ b denotes base
○ h denotes height
Here,
- Base of the parallelogram is 6 units and height is 4 units.
→ Area of the parallelogram = 6 units × 4 units
→ Area of the parallelogram = 24 units²
<u>Area</u><u> </u><u>of</u><u> </u><u>the </u><u>paral</u><u>lelogram</u><u> </u><u>is</u><u> </u><u>2</u><u>4</u><u> </u><u>units</u><u>²</u><u>.</u>

- Perimeter of parallelogram = Sum of all sides
Since, opposite sides of a parallelogram are equal. So,
○ First side = 6 units
○ Second side = 5 units
○ Third side = 6 units
○ Fourth side = 5 units
→ Perimeter = ( 6 + 5 + 6 + 5 ) units
→ Perimeter = ( 12 + 10 ) units
→ Perimeter = 22 units
<u>Perime</u><u>ter</u><u> of the parallelogram is 2</u><u>2</u><u> </u><u>units.</u>
