A relative skill level of 1420 represents a critically low skill level in the league. The management of your team has hypothesized that the average relative skill level of your team in the years 2013-2015 is greater than 1420. Test this claim using a 5% level of significance. For this test, assume that the population standard deviation for relative skill level is unknown Make the following edits to the code block below. 1. Replace ??DATAFRAME_YOUR TEAM?? with the name of your team's dalaframe. See Step 2 for the name of your team's dataframe.
2. Replace ??RELATIVE_SKILL?? with the name of the variable for relative skill see the table included in the Project Two instructions above to pick the variable name Enclose this variable in single quotes. For example, if the variable name is var2 then replace ??RELATIVE SKILL?? with var2
3. Replace ??NULL HYPOTHESIS VALUE?? with the mean value of the relative skill under the null hypothesis.

Choose the correct citation for the case which established the "minimum contacts" test for a court's jurisdiction in a case. select one: a. brown v. board of education of topeka, 347 u.s. 483 (1954). b. international shoe co. v. washington, 326 u.s. 310 (1945) c. haynes v. gore, 531 u.s. 98 (2000). d. international shoe co. v. washington, 14 u.s. code 336.

Write a program that displays the following menu: geometry calculator 1. calculate the area of a circle 2. calculate the area of a rectangle 3. calculate the area of a triangle 4. quit enter your choice (1-4): if the user enters 1, the program should ask for the radius of the circle and then display its area. use the following formula: area = ď€(the square of r) use 3.14159 for ď€ and the radius of the circle for r. if the user enters 2, the program should ask for the length and width of the rectangle and then display the rectangle’s area. use the following formula: area = length * width if the user enters 3, the program should ask for the length of the triangle’s base and its height, and then display its area. use the following formula: area = base * height * .5 if the user enters 4, the program should end. input validation: display an error message if the user enters a number outside the range of 1 through 4 when selecting an item from the menu. do not accept negative values for the circle’s radius, the rectangle’s length or width, or the triangle’s base or height. note: if the user enters an improper menu choice (1-4), the program prints "the valid choices are 1 through 4. run the program again and select one of those." if the user enters a negative radius, the program prints "the radius can not be less than zero." if the user enters a negative value for height or base, the program prints "only enter positive values for base and height."
