1(a) A research question that asks - What is the mean number of characters used in the names of NZ "data businesses" in the researcher's sample? - would require a sample-to-population inference

The researcher then carried out a similar sampling and inference approach but focused on comparing "human businesses" (businesses with the word "human" in their name and "psychology businesses" (businesses with the word "psychology" in their name). Compare the two different statements shown below, in terms of the strength of evidence and the provided confidence interval. One of these statements is incorrect and one is correct .Statement A There is some evidence that for all currently registered businesses, the mean years since a "human business* was registered is higher than the mean years since a "psychology business" was registered. Difference in group means with 95% Confidence human- psychology Estimate 3.135 Lower 0.439 Upper 5.832 Statement B There is strong evidence that for all currently registered businesses, the mean years since a "human business* was registered is higher than the mean years since a "psychology business" was registered. Difference in group means with 95% Confidence human- psychology Estimate 1.135 Lower -1.561 Upper 3.832 Clearly identify which one of the two statements is incorrect, by stating Statement A or Statement B. explain no more than two sentences
