Answer: x=4
Step-by-step explanation:
2x+14=22
14-14 22-14
2x=8
8/2
x=4
Answer:
There is no mode !
Step-by-step explanation:
Hello,
what is the mode of a set of data?
It is the value in the set that occurs most often.
To note that this is also possible to have a set of data with no mode.
in this example, let's order them
7, 8, 11, 12, 13, 14, 15, 20
There is no repetition, right? each value occurs only once.
So, there is no mode!
hope this helps
36 because 55 divided by 5 equals 11 and 11 x 2 = 22 and 35 ÷ 5 equals 7 and 7× 2 equals 14 and 14+22=36
Answer:
a
The null hypothesis is
The alternative hypothesis is
b
c
The decision rule is
Reject the null hypothesis
d
The conclusion is
There is no sufficient evidence to conclude that the variance of the immune response is equal to 1.9.
Step-by-step explanation:
From the question we are are told that
The variance is
The sample size is n = 30
The sample variance is
The level of significance is
The null hypothesis is
The alternative hypothesis is
Generally the test statistics is mathematically represented as
=>
=>
Generally from the degree of freedom is mathematically represented as
=>
=>
Generally from the chi distribution table the critical value of at a degree of freedom of is
=>
Gnerally from the values obtained we see that
hence
The decision rule is
Reject the null hypothesis
The conclusion is
There is no sufficient evidence to conclude that the variance of the immune response is equal to 1.9.
