Answer:
$836.8
Step-by-step explanation:
Average price = mean = $965
Standard deviation, = $100
Given that distribution is approximately normal ;
The least expensive 10% of the laptops :
We Obtain the Zscore that corresponds to P(Z ≤ 0.1) ; this means the least 10% of the laptops ;
From, a normal probability distribution table ;
P(Z ≤ 0.1) = - 1.282
We substitute this into the Zscore formula :
Zscore = (x - mean ) / standard deviation
x = price
-1.282 = (x - 965) / 100
-128.2 = (x - 965)
x = - 128.2 + 965
x = $836.8
Hence, price is $836.8
