In recent years, the interest rates on home mortgages have declined to less than 6%. However, a recent study shows that the rate charged on credit card debt is more than 14%. A sample of 10 credit
cards showed that the mean rate charged is 15.64% with a standard deviation of 1.561%. At 1% level
of significance, is it reasonable to conclude the mean rate charged is greater than 14%?

Yes it is reasonable to conclude the mean rate charged is greater than 14%

Step-by-step explanation:

From the question we are told that

    The  population mean is  

    The sample size is  

    The  sample mean is  

     The  standard deviation is  

     The level of significance is  

The null hypothesis is    

The  alternative hypothesis is  

 Generally the test statistic is mathematically represented as

substituting values

Now the p-value obtained from the z-table is

Since the then we reject the null hypothesis, hence we can conclude that  the mean rate charged is greater than 14%

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.

the answer would be c:   ax + b = ax + c
