A consumer claims that car model of type 1 has a lower average miles per gallon than all other cars on the market. Which of the following is the correct null hypothesis?Question 11Answera.µ < µ0b.µ = µ0c.µ ≥ µ0d.µ > µ0

A car manufacturer advertises that its new subcompact models get 47 miles per gallon (mpg). Let µ be the mean of the mileage distribution for these cars. You assume that the manufacturer will not underrate the car, but you suspect that the mileage might be overrated. State the null hypothesis and the alternate hypothesis for this case.a.H0: µ = 47mpg  and H1: µ ≠ 47mpgb.H0: µ = 47mpg  and H1: µ < 47mpgc.H0: µ = 47mpg  and H1: µ > 47mpgd.H0: µ ≥ 47mpg  and H1: µ < 47mpg

μ = 196.6 is an example of a null hypothesis expressed formally. True or false

The statement of the alternative hypothesis Ha: μ1 - μ2 < 0, states:Question 5Select one:a.that population mean 1 is smaller than population mean 2.b.that population mean 2 is smaller than population mean 1.c.that population mean 1 is larger than population mean 2.d.that the two population means are the same.

Which of the following options hold true for the null hypothesis?Note: Multiple options can be correct.The claim with only the ‘less than’ signThe claim with the ‘less than or equal to’ signThe claim with the ‘equal to’ signThe claim with the ‘not equal to’ sign

Which of the following would be an appropriate null hypothesis?
