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:
Dustin has 42 cards.
Mike has 54 cards.
Kevin has 39 cards
Step-by-step explanation:
subtract (Dustin + Mike) – (Dustin + Kevin) or 96 – 81.
Think of it like....
Dustin + Mike – Dustin – Kevin
Dustin – Dustin + Mike – Kevin
Mike – Kevin
Since 96 – 81 = 15, Mike – Kevin = 15
Add (Kevin + Mike) + (Mike – Kevin) or 93 + 15.
Think of it like...
Kevin + Mike + Mike – Kevin
Kevin – Kevin + Mike + Mike
Mike + Mike
Since 93 + 15 = 108, Mike + Mike = 108. If you divide, Mike had 54 cards. That means that you can find Kevin’s cards by using 93 – 54 or 39. You can then find Dustin’s cards by using 81 – 39 = 42.
Check:
Dustin’s cards + Kevin’s cards = 42 + 39 = 81
Dustin’s cards + Mike’s cards = 42 + 54 = 96
Mike’s cards + Kevin’s cards = 54 + 39 = 93
