Answer:

The value is $P( 1.39 < z < 1.53 ) = 0.0193$

Step-by-step explanation:

From the question we are told to obtain the area to the of the z-score 1.39 and to the left of the z-score 1.53, this is mathematically represented as

$P( 1.39 < z < 1.53 ) = P( z < 1.53 ) - P( z < 1.39 )$

From the z table on the question the area under the normal curve to the left corresponding to 1.53 and 1.39 is

$P( z < 1.53 ) = 0.9370$

and

$P( z < 1.39 ) = 0.9177$

$P( 1.39 < z < 1.53 ) = 0.9370 - 0.9177$

=> $P( 1.39 < z < 1.53 ) = 0.0193$
