Sergio [31]

Answer:

Step-by-step explanation:

Given that in  a study of computer use, 1000 randomly selected Canadian Internet users were asked how much time they spend using the Internet in a typical week (Ipsos Reid, August 9, 2005). The mean of the sample observations was 12.7 hours.

a) H_0: \bar x =12.5\\H_a: \bar x >12.5

(right tailed test at 5% level)

\sigma = 5\\std error = \frac{5}{\sqrt{1000} } \\=0.158

test statistic Z = Mean diff/std error = 1.265

(Here z test is used because sigma is known)

p value = 0.103

Since p >0.05, we accept H0

b) Here s= 2 hours.

But sample size is very large so z test is used.

Std error = \frac{2}{\sqrt{1000} } \\=0.0632

Test statistic = 3.16

p value =0.000783

since p <alpha, H0 is rejected

c) Because std deviation was less in part B, we got p value very low thus making us reject H0 in part B.

Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is 5.9 parts
GarryVolchara [31]

Answer:

t = -0.061

Step-by-step explanation:

We are given;

Population mean; μ = 5.9

Sample mean; x¯ = 5.6

Sample size; n = 24

standard deviation; σ = 1

Significance level = 0.02

Formula for the test statistic since sample size is less than 30 is;

t = (x¯ - μ)/(σ/√n)

t = (5.6 - 5.9)/(1/√24)

t = -0.3/(1/√24)

t = -0.061
