Answer:
x>3
Step-by-step explanation:
8x - 2x > 12+ 6
-> 6x > 18
-> x > 3
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.

Answer:
Test statistics of <u>1.455 </u>
P-value = 0.0728
Step-by-step explanation:
From the given information:
The test statistics can be computed as:

Z = 1.455
We want to test if the customer satisfaction increased significantly(one-tailed test)
Null hypothesis:

Alternative hypothesis:

P-value = P(Z>1.455)
= 0.0728
b) Type II error implies the error of accepting
when
is true.
This implies inferring that there is no huge improvement in passenger's satisfaction when there is.
c) Type 1 and Type II errors are inversely proportional. In this situation, as one increases, the other definitely decreases.
∴ A Smaller value of Type II error will be achieved by a higher type I error.
⇒ 0.10
