The level of significance associated with a significance test is the probability A) of rejecting a true null hypothesis.  B) of not rejecting a true null hypothesis.  C) that the null hypothesis is true.  D) that the alternative hypothesis is true.  Feedback: This level of significance, commonly set to α equal to 0.05, is used to set

0.00114 is less than the α value of 0.05. Therefore, H0 would be rejected at the level of significance 0.05 and the magazine price could be raised.

The mean time an American family lives in a particular single-family dwelling is 11.8 years. A sample of 100 families in the Sycamore, OK area shows the mean time living in a single family residence is 12.7 years. Can we conclude that the time people live in Sycamore is significantly more than the national average? One Sample Z-Test

Abstract This study investigated the effects of displaced objects and spatial reorganization on habituation of exploratory behavior. The subjects, rats, each individually spent 5 minutes in an open field for 6 trials. Throughout the study, exploratory behavior was measured in the number of contacts the subject made, the number of ambulations, and contact time (seconds). Trials 1-5 were mainly used to familiarize the subject with its surroundings, naturally leading to decreasing amounts of exploratory

as a branch of mathematics used to analyze, explain summarize as well as interpret what we observe- in order to make sense or meaning of our observations. Every day in life we encounter information that originates from diverse forms and ways. This means that to make this information to have sense, there is the need to use statistics. However, due to its focus and empirical on applications, statistics is classically considered a distinctive mathematical science rather than a branch of mathematics (Chance
