Answer #1

Here,

For given problem the hypothesis is

H0: The level of management is not significantly related to concern regarding the environment.

i.e. ( There no significant relationship)

H1: The level of management is significantly related to concern regarding the environment.

. ( There is significant relationship)

Here, tcal = 0.85 and ttable = 0.250

We know that, if tcal > ttable then we reject the null hypothesis

Here tcal = 0.85 > ttable = 0.250

So here we reject the null hypothesis i.e. H0

i.e. There is significantly relationship

So the correct option is C) The level of management is significantly related to concern regarding the environment.

The correlation coefficient r is a sample statistic. What does it tell us about the value of the population correlation coefficient ρ (Greek letter rho)? You do not know how to build the formal structure of hypothesis tests of ρ yet. However, there is a quick way to determine if the sample evidence based on ρ is strong enough to conclude that there is some population correlation between the variables. In other words, we can use the value of r...
