Use Zeller’s algorithm to figure out the days of the week for a given date in c.

W = (d + 13(m+1)/5 + y + y/4 + c/4 - 2c + 6) mod 7

Y is the year minus 1 for January or February, and the year for any other month

y is the last 2 digits of Y

c is the first 2 digits of Y

d is the day of the month (1 to 31)

m is the shifted month (March=3,...January = 13, February=14)

w is the day of week (0=Sunday,..,6=Saturday)

Output should look the following:

Please enter the day [YYYY/Month/Day]: 2020/1/1

Wednesday

To study the effect of overfishing in the Indian ocean investigators compared fishing areas in north that had never been overfished (Group 1) with similar areas nearby that had been overfished 1 year earlier (Group 2) and 8 years earlier (Group 3). Assume plots are randomly selected. The variable “Fishes” is the count of fish in an area. Using the data below decide whether the average number of fish differ among areas?

A vase U1 contains 2 white balls, a vase U2 contains 2 red balls, a vase U3 contains 2 white balls and 2 red balls and vase U4 contains 3 white balls and 1 red ball. The probability of choosing vase U1, U2, U3, and U4 are respectively 1/2, 1/4, 1/8 and 1/8. A vase is chosen and we retrieve the ball inside. Determine

a) The probability that the retrieved ball is white

b) Knowing the retrieved ball is white what is the probability that the ball was retrieved from vase U3.
