Use a Standard Spreadsheet Program, Such as Excel, to Find $X _ { \mathrm {10 } } ^ { 2 }$

Use a standard spreadsheet program, such as Excel, to find the following probabilities from various distributions analyzed in the current chapter:
a. If Y is distributed , find Pr(Y ? 7.78)
b. If Y is distributed $X _ { \mathrm {10 } } ^ { 2 }$ , find Pr(Y > 18.31)
c. If Y is distributed F_10,?, find Pr(Y > 1.83)
d. If Y is distributed t₁₅, find Pr(Y > 1.75)
e. If Y is distributed t₉₀, find Pr(-1.99 ?Y ? 1.99)
f. If Y is distributed N(0,1), find Pr(-1.99 ?Y ? 1.99)
g. If Y is distributed F_10,4, find Pr(Y > 4.12)
h. If Y is distributed F_7,120, find Pr(Y > 2.79)
