If the null hypothesis of an experiment is “The true mean weight of the geese is greater than 40 pounds” what is the alternate h
1 answer:
Answer:
<em>The true average weight of geese is less than or equal to 40 pounds</em>
Step-by-step explanation:
The null hypothesis and the alternative hypothesis are two mutually exclusive statements or hypotheses that are made about a population. The purpose is to find out if, through a study of the data, sufficient evidence is obtained to reject one and accept another
The null hypothesis is denoted as and the alternative hypothesis as
As they are two mutually exclusive statements then if
: <em>"The true average weight of the geese is greater than 40 pounds"</em>
the alternative hypothesis must be the opposite of the null hypothesis
: <em>"The true average weight of geese is less than or equal to 40 pounds"</em>

Answer : P(second resistor is 100ω , given that the first resistor is 50ω) is given by
Explanation :
Since we have given that
Total number of resistors =15
Number of resistors labelled with 50ω = 12
Number of resistors labelled with 100ω =3
Let A: Event getting resistor with 50ω
B: Event getting resistor with 100ω
Since A and B are independent events .
So,
Now, According to question , we can get that
So,
So, by using the conditional probability , which state that
So, P(second resistor is 100ω , given that the first resistor is 50ω) is given by
