Answer: d. There is no relationship between education level and smoking habits.
Step-by-step explanation:
The null hypothesis is the affirmation that two parameters or phenomena do not have a relation between them.
Here the parameters are smoking and having a bachelor's degree or higher education.
Then the null hypothesis says that those two things do not have any relation, this would imply that the probability of being a smoker does not depend on having a degree or not.
Then the correct option is d "There is no relationship between education level and smoking habits."
I think the answer is either 3/49 or about 0.061
hope this helps.
Answer:
approximately 27 grams
Work Shown:
Half life formula
y = A*(0.5)^(x/H)
where,
A = starting amount = 30 grams
H = half life period = 90 years
x = number of years that pass by = 12
y = amount left over after x years
Let's plug the values for x, A and H into the formula to find y
y = A*(0.5)^(x/H)
y = 30*(0.5)^(12/90)
y = 27.3516746567466
y = 27 .... rounding to the nearest whole number
Current Account Balance = $1,624.35
Initial Deposit = $975
Interest Rate (Simple) = 3.7% simple interest
Interest Earned = Current Account Balance - Initial Deposit
⇒ Interest Earned = $1,624.35 - $975
⇒ Interest Earned = $649.35
Now the Formula for Simple Interest is:
Simple Interest = ×
, where P is the initial deposit, R is the rate of interest and T is the time period
⇒ 649.35 = 
⇒ T = 
⇒ T = 18
Hence, Jeremiah has had the account for 18 years.
