Answer:

It is not a binomial experiment because the random variable associated with this experiment is a Geometric random variable.

Step-by-step explanation:

For an experiment to be a binomial experiment the variable associated with the experiment has to be a binomial random variable.

A binomial random variable should satisfy the following conditions:

There should be a fixed known no. of trials
There should be only 2 outcomes of a trial i.e either success or failure
Trial results should be independent
Same probability for each trial success or failure

Now lets see what is the random variable in this experiment:

The Random variable would be X = no. of selections until a defective one is found.

X does not satisfy the first condition for a binomial variable itself as the no. of trials is not fixed and is unknown.

Hence X is not a binomial random variable.

Rather X is a Geometric random variable. If we consider finding a defective one as a success then the variable is defined as the no. of trials until a success is achieved. But a binomial random variable is defined by no. of successes in a fixed no. of trials.

Hence it is not a binomial experiment .

Answer:

It is not a binomial experiment

Step-by-step explanation:

For an experiment to be a binomial, the variable associated with the experiment has to be a binomial random variable.

A binomial random variable should satisfy the following conditions:

1. There should be a fixed known number of trials .

2.There should be only 2 outcomes of a trial i.e. either success or failure

3. Trial results should be independent

4. Same probability for each trial success or failure

The Random variable in this experiment is X = no. of selections until a defective one is found.

Now here,X does not satisfy the first condition for a binomial variable itself as the no. of trials is not fixed and is unknown.

Hence X is not a binomial random variable.

So this experiment is not binomial experiment.

Half of a number plus 12 is 46

asambeis [7]

Let the number = x
x/2 + 12 = 46
x/2 = 46 - 12
x/2 = 34
x = 34 * 2
x = 68

So, your final answer is 68

Hope this helps!

Consider the age distribution in the United States in the year 2075 (as projected by the Census Bureau). Construct a cumulative

MrRissso [65]

Answer:

The cumulative frequency plot is also attached below.

Step-by-step explanation:

The data provided is as follows:

Age Group Frequency

0 - 9 34.9

10 - 19 35.7

20 - 29 36.8

30 - 39 38.1

40 - 49 37.8

50 - 59 37.8

60 - 69 34.5

70 - 79 27.2

80 - 89 18.8

90 - 99 7.7

100 - 109 1.7

Consider the Excel output attached.

The cumulative frequency are computed in the Excel sheet.

The cumulative frequency plot is also attached below.

From the cumulative frequency plot it can be seen that in the future most people will belong to a higher age group rather then the lower ones.
