Answer 1

Answer:

III. There is evidence that the program improved employees attitudes towards innovativeness and change.

Explanation:

In statistics,  null hypothesis is the general statement or predefined position which states that there is no significant different happening, that is there is no such association between the groups or variables, or no two measured phenomena are inter related.

In the context,

The program have not improved the employees' attitude toward change and innovativeness , therefore

H0: Null hypothesis: p = 0.15

Therefore we know that 0.15 is not within the Confidence Interval. So, H0 will be rejected.

Also, all the values in the Confidence interval are greater than 0.15.

Hence

There is evidence that the program improved employees' attitudes towards innovativeness and change.

Thus the correct answer is -- (III)
