Answer:
[tex]P(x<10miles)=0.023[/tex]
Step-by-step explanation:
From the question we are told that
Sample mean [tex]\=x=12.4[/tex]
Standard deviation [tex]\sigma=1.2miles\ per\ gallon[/tex]
Probability of [tex]P(x<10miles)[/tex]
Generally the equation for [tex]P(x<10miles)[/tex] is mathematically given as
[tex]P(x<10miles)=(\frac{10-12.4}{1.2})[/tex]
[tex]P(x<10miles)=0.023[/tex]
Therefore The probability that a randomly selected truck averages fewer than 10 miles per gallon
[tex]P(x<10miles)=0.023[/tex]
