The cost of one ounce each :
$2.29/22.3 = $0.10
$3.00/12.5 = $0.24
$5.16/32 = $0.17

The order

Answer:

Best fruit <Smooth and Tasty<Healthy Smoothie

Step-by-step explanation:

A) Best Fruit 22.5 ounces for $2.29

Cost of 22.5 ounces of Best fruit = $2.29

Cost of 1 ounce of Best fruit = \frac{2.29}{22.5}=0.101

B)Healthy Smoothie 12.5 ounces for $3.00

Cost of 12.5 ounces of Healthy Smoothie= $3

Cost of 1 ounce of Healthy Smoothie = \frac{3}{12.5}=0.24

C)Smooth and Tasty 32 ounces for $5.16

Cost of 32 ounces of Smooth and Tasty = $5.16

Cost of 1 ounce of Smooth and Tasty  = \frac{5.16}{32}=0.161

the least to the greatest unit cost in dollars per ounce.: 0.101<0.161<0.24

Best fruit <Smooth and Tasty<Healthy Smoothie

The Wall Street Journal reports that 33% of taxpayers with adjusted gross incomes between $30,000 and $60,000 itemized deduction
Len [333]

Answer:

(a) <em>                             </em><em>n</em> :      20           50          100         500

P (-200 < <em>X</em> - <em>μ </em>< 200) : 0.2886    0.4444    0.5954    0.9376

(b) The correct option is (b).

Step-by-step explanation:

Let the random variable <em>X</em> represent the amount of deductions for taxpayers with adjusted gross incomes between $30,000 and $60,000 itemized deductions on their federal income tax return.

The mean amount of deductions is, <em>μ</em> = $16,642 and standard deviation is, <em>σ</em> = $2,400.

Assuming that the random variable <em>X </em>follows a normal distribution.

(a)

Compute the probability that a sample of taxpayers from this income group who have itemized deductions will show a sample mean within $200 of the population mean as follows:

  • For a sample size of <em>n</em> = 20

P(\mu-200

                                           =P(-0.37

  • For a sample size of <em>n</em> = 50

P(\mu-200

                                           =P(-0.59

  • For a sample size of <em>n</em> = 100

P(\mu-200

                                           =P(-0.83

  • For a sample size of <em>n</em> = 500

P(\mu-200

                                           =P(-1.86

<em>                                  n</em> :      20           50          100         500

P (-200 < <em>X</em> - <em>μ </em>< 200) : 0.2886    0.4444    0.5954    0.9376

(b)

The law of large numbers, in probability concept, states that as we increase the sample size, the mean of the sample (\bar x) approaches the whole population mean (\mu_{x}).

Consider the probabilities computed in part (a).

As the sample size increases from 20 to 500 the probability that the sample mean is within $200 of the population mean gets closer to 1.

So, a larger sample increases the probability that the sample mean will be within a specified distance of the population mean.

Thus, the correct option is (b).

A sociologist is studying the social media habits of high school students in a school district. The sociologist wants to estimat
Sindrei [870]

Answer:

A one-sample t-interval for a population mean

Step-by-step explanation:

As the question is "How many minutes per day, on average, do you spend visiting social media sites?", the answer will be in a numerical form (number of hours, positive integer or real number).

As this is not a proportion, the option "A one-sample t-interval for a population mean" is discarded.

As the study does not defined another variable to compare in pairs, it is not a matched-pairs test. Option "A matched-pairs t -interval for a mean difference" discarded.

There are not two means in the study, so there is no "difference between means" variable. Options "A two-sample z-interval for a difference between proportions" and "A two-sample t-interval for a difference between means".

This should be a  one-sample t-interval for a population mean, as there is only one sample, one population mean and the population standard deviation is not known.

maks197457 [2]
Arrivals at a fast-food restaurant follow a Poisson distribution with a mean arrival rate of 16 customers per hour. In the study of statistics and probability, the Poisson distribution is a widely-used discrete probability distribution. Using the formula, it was determined that 0.0661 is the probability that in the next hour there will be exactly 12 arrivals.
