Answer:

11/15

Step-by-step explanation:

If 4 out of 15 are Canadian, the ratio of the probability of picking a Canadian is 4/15.  That means that the probability of NOT picking a Canadian is the complement of 4/15 which is 11/15.  Therefore, the probability of not picking a Canadian is the same thing as the probability of picking an American penny which is 11/15.

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)

When beans are cooked, the amount of water required varies directly with the cups of beans. If 2 cups of beans require 4.5 cups
marishachu [46]

Answer:

11.25 cups of water is needed to cook 5 cups of Beans.

Step-by-step explanation:

Given:

The amount of water required varies directly with the cups of beans.

2 cups of beans require 4.5 cups of water.

we need to find how many cups of water are needed to prepare 5 cups of beans.

4.5 cups of water =2 cups of bean

Number of cups of water = 5 cups of bean.

Now Using Unitary method for solving above we get,

Number of cups of water required = \frac{5\times4.5}{2}=\frac{22.5}{2}=11.25 \ cups

Hence 11.25 cups of water is required to prepare 5 cups of beans.
