The movement of the unemployment rate and inflation rate has been inconsistent with a stable Phillips Curve
Step-by-step explanation:
The Phillips curve is an economic model suggesting a negative relationship between the unemployment rate and inflation. The model, therefore, implies that a fall in unemployment should lead to an increase in inflation. However, there is a doubts among economists about whether the Phillips curve is an appropriate model to forecast inflation. The doubt is based upon the issues which presented itself during, and after, the Great Recession. During the Recession, the U.S faced a rise in the unemployment rate and according to predictions from the Phillips curve, the rise in the unemployment rate should have yielded a greater decrease in inflation. Much greater than the decrease the U.S. experienced. It
seems like the relationship between inflation and unemployment, once regarded reliable, has weakened. Researchers have been trying to understand why inflation has been behaving in this way.
Answer:
Approximate probability that the number of households that use the Internet for banking in a sample of 1000 is less than or equal to 130 is less than 0.0005% .
Step-by-step explanation:
We are given that let X be the number that do some or all of their banking on the Internet.
Also; Mean, 
= 310/1000 or 0.31 and Standard deviation, 
= 14.63/1000 = 0.01463 .
We know that Z = 
~ N(0,1)
Probability that the number of households that use the Internet for banking in a sample of 1000 is less than or equal to 130 is given by P(X <= 130/1000);
P(X <=0.13) = P( <= 
) = P(Z <= -12.303) = P(Z > 12.303)
Since this value is not represented in the z table as the value is very high and z table is limited to x = 4.4172.
So, after seeing the table we can say that this probability is approximately less than 0.0005% .
