Answer: False
Nothing is 100% certain no matter how sure it seems. This is especially true with statistics. There's always going to be some amount of error. The goal is to minimize the error as much as possible in the best cost-effective manner.
Answer:
1. 4/12 , 6/8
2. 16/12 , 3/4*
3. 3/2 , 15/14
4. 10/16 , 5/8
10/16 = 5/8
Which ratio forms a proportion with 9/15?
1. 6/10
2. 16/21
3. 36/50
4. 45/70
9/15 = 3/5 which is 6/10
A textbook weighs 2.5 pounds. How many kilograms does the textbook weighs? Round your answer to the nearest tenth of a pound. 1 kg = 2.2 lb
1. 1.1 kg
2. 1.8 kg
3. 5.5 kg
4. 4.7 kg
2.5 lbs * (1 kg/2.2 lbs) =
Solve the proportion using number sense. 2/8 = x/ 48
1. 6
2. 12
3. 16
4. 8
8 * 6 = 48
so what is 2 times 6 ?
or another way
1/4 * 48 = 12
Solve the proportion using cross products. 18/20 = k/110
1. 99
2. 122
3. 3.3
4. 2.9
20 k = 18*110
2 k = 18 *11
k = 9 * 11
Are the ratios 8/12 and 10/25 proportional? Explain
8/12 = 2/3
10/15 = 2/3 so no way 10/25 is 2/3
A 10-acre field produced 750 bushels of corn. At the rate, how much corn can be produced from a 14-acre field?
14 acres * ( 75 bushels/acre)
or
10/750 = 14/x

Answer:
d. H0: melanoma mortality rate is not linearly related to latitude
Ha: melanoma mortality rate is linearly related to latitude
Step-by-step explanation:
The linear regression equation is
y=α+βx where α=intercept and β=slope.
β=slope demonstrates the change in dependent variable due to unit change in independent variable.
If the slope is zero then we can say that Y and X are not linearly related.
Thus, the hypothesis for testing significance of linear relationship two variables can be written as
Null hypothesis: The two variables are not linearly related i.e. β=0
Alternative hypothesis : The two variables are linearly related i.e. β≠0.
Thus, in the given scenario the hypothesis are
H0: melanoma mortality rate is not linearly related to latitude
Ha: melanoma mortality rate is linearly related to latitude.
