What is the value to P(-1.22<Z<9.43)? Please report your answer in 3 decimal places.

Expert Solution

P(-1.22 < Z < 9.43) = P(Z < 9.43) - P(Z < -1.22)

= 1 - 0.1112

= 0.8888

= 0.889 (ans)

4) • z-value should be expressed to three decimal places: e.g., z=1.645. • Before you start each question, you should determine if you are dealing with the population mean or proportion since what you do depends on the type of parameter at hand. • When handling proportion problems, write/use/plug proportions as decimals (e.g., not 54%, but .54). • In the beginning, state clearly if you do a 1-tailed or 2-tailed test. State clearly your H0 and H1 using correct Greek...
