natali 33 [55]

Answer:

98% confidence interval: (29.25,38.87)

Step-by-step explanation:

We are given the following in the question:

Sample mean, \bar{x} = 34.06

Sample size, n = 134

Sample standard deviation, s = 23.83

a) 98% confidence interval

\bar{x} \pm z_{critical}\displaystyle\frac{s}{\sqrt{n}}  

Putting the values, we get,  

z_{critical}\text{ at}~\alpha_{0.02} = \pm 2.33  

34.06 \pm 2.33(\frac{23.83}{\sqrt{133}} ) = 34.06 \pm 4.81 = (29.25,38.87)

b)  If a 95% confidence interval were constructed with these data, confidence interval would be narrower as the confidence level is decreasing as compared to 98%

c)  If a sample of 150 students had been studied, the width of confidence interval will decrease as the sample size increases.

7+ 2x divided by 5= 13
Troyanec [42]

Answer:

x=29

Step-by-step explanation:

Given equation :

\frac{(7+2x)}{5} =13

Making the terms of 'x' to one side and constants to the other.

                   (7+2x)=13*5

                       7+2x=65

                            2x=65-7

                              2x=58

                                x=\frac{58}{2}

                                  x=29

So, the value of 'x' is 29.
