Which of the following statements about the Null Hypothesis Decision Strategy is false?
Group of answer choices
As a last step, we state whether our scientific hypothesis is actually true or not
The logic of NHDS is much the same for all research scenarios except for when we have categorical response variables
Confidence in our conclusions about our population of interest is greater when we are able to obtain a random as opposed to a nonrandom sample from that population
NHDS is dependent on the alternative hypothesis informing us about what sample outcomes we should expect to occur as a result of sampling error.

Which one the following statements is false about the null hypothesis? It is the hypothesis that the observed correlation is the result of random fluctuation. The likelihood of observing the results that we observed if this hypothesis is true, is the p-value. It is the hypothesis that would be wrong in case our causal hypothesis is true. The hypothesis that our causal explanation is true and explains the observed correlation.

Question 3 options: We use the normal distribution when we conduct a hypothesis test about a population mean. We use the t-distribution when we conduct a hypothesis test about a population proportion. Researchers get to choose the significance level. A few popular choices are 10%, 5% and 1%. However, it is not possible to choose 0%! We...

7. Hypothesis tests about a population proportion A firm's corporate strategy is driven largely by its top management team. One method of gauging the influence of marketing on corporate strategy is to measure the proportion of firms with a chief marketing officer on their top management team. Over the 5-year period from 2000 to 2004, 42% of firms had a chief marketing officer on their top management team. [Source: Pravin Nath and Vijay Mahajan, "Chief Marketing Officers: A Study of...
