Answer: _______________0.3809_______________________
Q3: P (k ≤ Z ) ≈ 0.8749, k = ?
Answer: _________________-1.15_____________________
Q4: P ( Z ≥ -0.30 | Z ≥ -1.83 ) = ?
Answer: ________________0.6394___________________
Q5: P ( Z ≤ 0.76 | Z ≥ -0.24) = ?
Answer: ________________0.6241__________________
Q 1)
Q 2_)
Q 3 )
Using Standard normal table the corresponding value of Z for the area 0.3749 is -1.15
Therefore k = -1.15
