A newspaper reported the results of a survey on the planning habits of men and women. In response to the question​ "What is your

preferred method of planning and keeping track of​ meetings, appointments, and​ deadlines?" 54​% of the men and 44​% of the women answered​ "I keep them in my​ head." A nationally representative sample of​ 1,000 adults participated in the​ survey; therefore, assume that 500 were men and 500 were women. Complete parts a through e. a. Set up the null and alternative hypotheses for testing whether the percentage of men who prefer keeping track of appointments in their​ head, p 1​, is larger than the corresponding percentage of​ women, p 2. Choose the correct answer below.

Answer:

H₀: p₁ - p₂ = 0

H₁: p₁ - p₂ > 0

Step-by-step explanation:

A null hypothesis is a hypothesis that says that there's no statistical relation between the variables/data.

On the other hand, and alternative hypothesis says that there is a statistical relation between the variables. And this hypothesis is what the researcher wants to prove.

The null and alternative hypotheses are mutually exclusive.

In the present problem, what needs to be tested is <u>whether the percentage of men who prefer keeping track of appointments in their head p₁ is larger than the percentage of women p₂.</u>

Our null hypothesis would be the one that states that there's no statistical relation between p₁ and p₂. In other words, the percentage of men who prefer keeping track in their head is not larger than women's percent. Therefore

H₀: p₁ - p₂ = 0

Our alternative hypothesis would indicate that there is a statistical relation between the variables. Since t<u>he researcher wants to prove that a larger percentage of men keep track of appointments in their head</u> in comparison with women, this would be that p₁ is in fact larger than p₂

H₁: p₁ - p₂ > 0

What is the messure of N and the two angles; an-16 and 6n
AURORKA [14]

Answer:

14, 96,84

Step-by-step explanation:

8n  - 16 + 6n = 180 {Supplementary angles}

<u>8n + 6n</u>  -16 = 180

Combine like terms

14n - 16 = 180

Add 16 to both sides

14n = 180 + 16

14n = 196

Divide both sides by 14

n = 196/14

n = 14

8n - 16 = 8*14 - 16 = 112 - 16 = 96

6n = 6 *14 = 84

Two men walk at rates of 6 miles per hour and 10 miles per hour, respectively. Simultaneously, they started from the same place
alina1380 [7]

The time taken by the two men will be equal to 26 hours

<h3>What is speed?</h3>

The speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance.

here two men are walking at different speeds like

v₁=6 miles per hour

v₂=10 miles per hour

The time taken by them to separated by the distance of 100 miles each so that both of them separated by the distance of 200 miles.

t₁= {100}/{6}=16.66 hours

t₂= {100}/{10}=10 hours

total time taken will be

t₁+t₂=16.66+10=26.66 hours

The times to process orders at the service counter of a pharmacy are exponentially distributed with mean 1 0 minutes. If 100 cus
g100num [7]

Answer:

Therefore,  the probability that at least half of them need to wait more than 10 minutes is <em>0.0031</em>.

Step-by-step explanation:

The formula for the probability of an exponential distribution is:

P(x < b) = 1 - e^(b/3)

Using the complement rule, we can determine the probability of a customer having to wait more than 10 minutes, by:

p = P(x > 10)

  = 1 - P(x < 10)

  = 1 - (1 - e^(-10/10) )

  = e⁻¹

  = 0.3679

The z-score is the difference in sample size and the population mean, divided by the standard deviation:

z = (p' - p) / √[p(1 - p) / n]

  = (0.5 - 0.3679) / √[0.3679(1 - 0.3679) / 100)]

  = 2.7393

Therefore, using the probability table, you find that the corresponding probability is:

P(p' ≥ 0.5) = P(z > 2.7393)

<em>P(p' ≥ 0.5) = 0.0031</em>

<em></em>

Therefore,  the probability that at least half of them need to wait more than 10 minutes is <em>0.0031</em>.
