g100num [7]

Answer:  54 mph

Step-by-step explanation:

d-the distance

s+9  -  the speed to the conference

d=6*(s+9)

s- is the speed on the way back home

d=7*s

so    6*(s+9)=7*s

       6s+54=7s

     -6s          -6s

       54= 7s-6s

       s=54  mph

The USA Today reports that the average expenditure on Valentine's Day is $100.89. Do male and female consumers differ in the amo
sergeinik [125]

Answer: $ 67.03

Step-by-step explanation:

Given : The average expenditure in a sample survey of 50 male consumers was $135.67, and the average expenditure in a sample survey of 38 female consumers was $68.64.

i.e. \overline{x}_1=\$135.67\ \ \&\ \ \overline{x}_2=\$68.64

The best point estimate of the difference between the two population means is given by :-

\overline{x}_1-\overline{x}_2\\\\=135.67-68.64=67.03

Hence, the point estimate of the difference between the population mean expenditure for males and the population mean expenditure for females : $ 67.03
