Answer 1

Answer:

a) $P(-1.45$

b) $P(-1.63$

c) $P(-1.48$

d) $P(-1.37$

Step-by-step explanation:

To find : Determine the area under the standard normal curve that lies ?

Solution :

a) In between Z=-1.45 and Z=1.45

i.e. $P(-1.45$

Now, $P(-1.45$

Using Z-table,

$P(-1.45$

$P(-1.45$

b) In between Z=-1.63 and Z=1.63

i.e. $P(-1.63$

Now, $P(-1.63$

Using Z-table,

$P(-1.63$

$P(-1.63$

c) In between Z=-1.48 and Z=1.48

i.e. $P(-1.48$

Now, $P(-1.48$

Using Z-table,

$P(-1.48$

$P(-1.48$

d) In between Z=-1.37 and Z=1.37

i.e. $P(-1.37$

Now, $P(-1.37$

Using Z-table,

$P(-1.37$

$P(-1.37$
