State the null and alternative hypotheses for the above scenario.

Answer:

The null hypothesis is  H_o :  p \le  0.41

The  alternative hypothesis  H_1  :  p> 0.41

Step-by-step explanation:

From the question we are told that

      The population proportion is p  =  0.41

        The level of significance is  \alpha  = 0.10

The null hypothesis is  H_o :  p \le  0.41

The  alternative hypothesis  H_1  :  p> 0.41

Katyanochek1 [597]

Answer:

(a) X(t)=X(0)+\Delta X*t=5-0.5*t

(b) X(t)=X(0)+\Delta X*t=1+0.5*t

(c) At 4 weeks, when both will be seeing an average of 3 hours of TV.

Step-by-step explanation:

a) For the students, they start at X(0)=5 h and ΔX=-0.5 h/week.

We can write

X(t)=X(0)+\Delta X*t=5-0.5*t

b) For the professors, they start at X(0)=1 h and ΔX=+0.5 h/week.

We can write

X(t)=X(0)+\Delta X*t=1+0.5*t

c) The seew which they will be watching the same amount of hours will be the 4th week.

X(t)=5-0.5*t=1+0.5*t\\\\5-1=(0.5+0.5)*t\\\\t=4\, weeks

The amount of hours will be

x(4)=1+0.5*4=1+2=3\,hours
