The company offers two types of sales: 1. Internet sales; 2. Store sales. The marketing research manager believes that the Internet sales are more than 10% higher than store sales. The null hypothesis would be:

Ho (null hypothesis) indicates no difference. Which choice does that indicate?

Not sure what no difference means. I was thinking that it was D for the answer but reading your response makes me think it may be E? If you can explain more that would be helpful. Thanks

To determine the null hypothesis in this scenario, we need to understand what it means for Internet sales to be more than 10% higher than store sales.

Let's start by defining the proportion of Internet sales as Pinternet and the proportion of store sales as Pstore.

Since we want to compare the two proportions, we can set up the following hypothesis:

Null hypothesis (H0): Pinternet - Pstore ≤ 0
Alternative hypothesis (Ha): Pinternet - Pstore > 0

In this case, the null hypothesis states that there is no significant difference between Internet sales and store sales, or that Internet sales are equal to or lower than store sales.

Based on the given options, the correct answer is:
C. Pinternet – Pstore less than or equal to 0.10
