Yesterday 11 inches of snow fell. Determine whether the data value is from a discrete or continuous data set. It is from a conti

nuous data set because the set has a finite number of possible values. It is from a continuous data set because the set has infinitely many possible values. It is from a discrete data set because the set has a finite number of possible values. It is from a discrete data set because the set has infinitely many possible values.

The <em>correct answer</em> is:


It is from a continuous data set because the set has infinitely many possible values.


Explanation:


A continuous data set is one that can be connected with lines or curves.


This means that all possible values between data points are included in the set as well. Generally, this includes decimals and fractions.


In terms of this problem, inches of snow, we can have 11 inches of snow or 12 inches of snow We can also have 11.1 inches of snow; 11.01 inches of snow; 11.001 inches of snow; etc.


This means it is a continuous data set.

Assume the general population gets an average of 7 hours of sleep per night. You randomly select 45 college students and survey
tekilochka [14]

Answer:

a) ii. This is a left-tailed test.

b) -1.59

c) -1.301

d) i. reject null hypothesis

e) Option i) The data supports the claim that college students get less sleep than the general population.

Step-by-step explanation:

We are given the following in the question:  

Population mean, μ = 7 hours

Sample mean, \bar{x} = 6.87 hours

Sample size, n = 45

Alpha, α = 0.10

Sample standard deviation, s =  0.55 hours

First, we design the null and the alternate hypothesis

H_{0}: \mu = 7\text{ hours}\\H_A: \mu < 7\text{ hours}

a) We use one-tailed(left) t test to perform this hypothesis.

b) Formula:

t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }

Putting all the values, we have

t_{stat} = \displaystyle\frac{6.87 - 7}{\frac{0.55}{\sqrt{45}} } =-1.59

c) Now,

t_{critical} \text{ at 0.10 level of significance, 44 degree of freedom } = -1.301

Since,                    

t_{stat} < t_{critical}

d) We fail to accept the null hypothesis and reject it.

We accept the alternate hypothesis and conclude that  mean number of hours of sleep for all college students is less than 7 hours.

e) Option i) The data supports the claim that college students get less sleep than the general population.
