Answer: 600

Step-by-step explanation: Let's first rewrite this problem to say 40% of what number is 240.

To answer the question 40% of what number is 240, we translate the question into an equation. First we have 40% which we need to write as a decimal. To write 40% as a decimal, we move the decimal point 2 places to the left. Filling in the missing position with a zero, we get 0.4.

Next we have "of what number" which means times x, "is 240" equals 240.

Now we have the equation (0.40)(x) = 240.

Now to solve for x, since x is being multiplied by 0.40, we need to divide by 0.40 on both sides of the equation. On the left side of the equation the 0.40's cancel and we have x. On the right side of the equation we have 240 divided by 0.40 which is 600.

This means that x = 600.

This means that 40% of 600 is 250.

During the first 13 weeks of the television season, the Saturday evening 8:00 p.m. to 9:00 p.m. audience proportions were record

SpyIntel [72]

Part 1: Do not reject H0. There has not been a significant change in the viewing audience proportions.(The above conclusion holds as the p-value is greater than the significance level of 0.05)

Part 2:

H0:

Ha:

Part 3: The test statistic is given as 3.0081.

Part 4: The p-value is given as 0.39037

Step-by-step explanation:

As per the data

Part 2

H0:

Ha:

Part 3

As per the sample is of 300 homes, the expected values are given as

ABC=p(ABC)*300=0.30*300=90

CBS=p(CBS)*300=0.27*300=81

NBC=p(NBC)*300=0.26*300=78

IND=p(IND)*300=0.17*300=51

Now the values actually are given as

ABC=94

CBS=71

NBC=88

IND=47

So the test static is given as

So the test statistic is given as 3.0081.

Part 4

Now the degree of freedoms are given as 4-1=3

and chi square is given as 3.0081 so for α = 0.05 , the p-value is given as 0.39037

Part 1.

As the value of p in part 4 is greater than the value of α = 0.05, thus Do not reject H0. There has not been a significant change in the viewing audience proportions.(The above conclusion holds as the p-value is greater than the significance level of 0.05)
