20: Assume that matched pairs of data result in the given number of signs when the value of the second variable is subtracted from the corresponding value of the first variable. There are 8 positive signs (+), 7 negative signs (−), and 2 ties (zeros). Using the sign test with ? = 0.05 significance level, state the test statistic, the critical value, and whether or not you would reject the null hypothesis of no difference in the variables. Test statistic = ____ ; Critical Value = _____ ; Reject or Fail to Reject Null Hypothesis?

The data below are the healing rates of cuts (micrometers per
hour) in a matched pairs experiment. The pairs are the two hind
limbs of the same newt. In each pair, one limb had reduced
electrical field and the other (the control) had its natural
electrical field.

Assume that 20 bytes of Packed BCD data is present in a data
memory at location 0x300 to 0x313. You have to write an assembly
program that will display data on a two seven segment displays one
connected to Port A and other connected to Port B using loops. You
also have to analyze data if the data is equal to 0x22 then start
storing data bytes at corresponding memory address 0x400 to 0x413
in reverse order i.e. if the...

A diagnostic test has a 95% probability of giving a positive
result when given to a person who has a certain disease. It has a
10% probability of giving a (false) positive result when given to a
person who doesn’t have the disease. It is estimated that 15% of
the population suffers from this disease.
(a) What is the probability that a test result is positive?
(b) A person recieves a positive test result. What is the
probability that this...

Assume the market demand curve is given by QM = 20 – P and the
fringe firm supply function is
QFF = -6+P. The dominant firm’s marginal cost is MC = 4 and fixed
costs are zero.
1. Using a new graph, explain what happens to residual demand
curve if the fringe supply curve becomes perfectly elastic at $6.
Further assume the dominant firm MC is upward slopping with an
equation of MC = -2 +Q. Same market demand function....
