Let Z be a standard normal variable. Find the value of z if z satisfies P(Z > z) = 0.6331.

alisha [4.7K]

Answer:

$z = -0.340$

Step-by-step explanation:

We are given that Z is a standard normal variable.

We have to find the value of z such that

P(Z > z) = 0.6331

$P( Z > z)=0.6331$

$= 1 -P( Z \leq z)=0.6331$

$=P( Z \leq z)=1 - 0.6331 = 0.3669$

Calculation the value from standard normal z table, we have,

$P(z \leq -0.340) = 0.3669$

Thus,

$z = -0.340$

Answer:

235or 236

Step-by-step explanation:

A cone has a radius of 5 cm

a height of 9 cm

Volume of cone =1/3πr^2h

=1/3×3.14×5×5×9

= 3.14×25×3

=3.14×75

=235.5
