Extracted text: A researcher is interested in whether a new reading technique influences the reading ability of elementary school children. The researcher knows that average reading ability among a population of third graders is µ = 3 with a standard deviation of o = 1. If the researcher administers the new reading technique to a third grader who subsequently scores X = 4, it can be concluded that the new reading technique decreases reading ability. does not have an influence on reading ability. does have an influence on reading ability. This cannot be determined based on the provided information.


Extracted text: A population has u = 50. Which value of o would make X= 55 an extreme value out in the tail of the population distribution? O o = 1 O o = 6 0 = 10 This is impossible to determine based on the information provided.
