The question requires stating the Null and Alternative hypothesis for the scenario described :
Answer:
H0 : μ = 24
H1 : μ < 24
Step-by-step explanation:
The claim or hypothesis to be tested in a statistical problem or analysis is the alternative hypothesis. This is usually the opposite of the Null hypothesis which is the usually the initial truth until there is significant evidence provided using statistical test to prove otherwise.
The null hypothesis, H0 in the scenario above is :
H0 : μ = 24 ( average battery life is 24 hours)
The alternative hypothesis is the claim, that is. The mean battery life not up to 24 hours ;
H1 : μ < 24
When you're given a point and the slope of a line, it is often easiest to write its equation in
point-slope form.
This is
, where
is the ordered pair for the point you are given and m is the slope.
Here, you would write
. Then, you simplify to get to
slope-intercept form, which is
, where b is the y-intercept.
The correct answer is A.
Answer:
The more fish Carl tests, the more likely he is to find a 30% parasite incidence rate.
Step-by-step explanation:
Given that fish inhabiting the river in the town of Glenmeadow have a 30% rate of parasite incidence
Carl is a fisherman who wants to verify the parasite infection rate of Glenmeadow's fish.
Sample size of 1000 i.e. 1000 fish is caught.
The interpretation of the given statement is
The more fish Carl tests, the more likely he is to find a 30% parasite incidence rate.
is the interpretation of population proportion rate for catching fish.
1: B $3.85
2: C The rabbit; 14 miles per hour
3: C 2 1/2 miles
1. Reason: To find the price per gallon, all you need to do is divide 46.20 by 12 to get 3.85
2. Reason: To find which animal is faster all you have to do is subtract the greater number, which is the rabbit that travels 35 miles per hour from the smaller number which is the fox that travels 21 miles.
Subtract: 35-21= 14. So the rabbit is faster by 14 miles.
3. Reason: If Randy walks 1/2 mile in every 1/5 hour, to find the much he will walk in a hour you could count up:
1/2 mile = 1/5 hour
1 mile = 2/5 hour
1 1/2 mile = 3/5 hour
2 mile = 4/5 hour
2 1/2 mile = 1 hour
So, Randy will travel 2 1/2 miles in a hour.
