It is unchanged because the same number would still be in the middle and there would still be the same amount of numbers
if
11,15,21,22,23,27,30 before 22 is the median
if
11,15,21,22,23,27,30 after 22 is still the median
The median is unchanged
Answer:
Step-by-step explanation:
Mixed fraction can be converted into like or unlike fractions.
Here,
So, convert all the given fractions as follows:
Here, No Two fractions on addition gives a sum greater than 5.
But an approximate sum of 5 is given by adding 2.4 + 2.6 = 5
⇒
or ⇒
Answer:
Step-by-step explanation:
First, find 40% of 3,000:
0.40 * 3000 = 1200
So they raised 1200 so far.
Now subtract 1200 from the total they want to raise:
3000 - 1200 = 1800
So they need $1,800 more to meet their goal.
Complete Question
A random sample of 300 circuits generated 13 defectives. a. Use the data to test
Versus
Use α = 0.05. Find the P-value for the test
Answer:
The p-value is
Step-by-step explanation:
From the question we are told that
The sample size is n = 300
The number of defective circuits is k = 13
Generally the sample proportion of defective circuits is mathematically represented as
=>
=>
Generally the standard Error is mathematically represented as
=>
=>
Generally the test statistics is mathematically represented as
=>
=>
From the z table the area under the normal curve to the left corresponding to -0.5317 is
Generally the p-value is mathematically represented as
=>
=>
