2.3.10 In Example 1.1, we looked at a study to investigate whether dolphins could communicate. In doing so, we tested whether Buzz, one of the dolphins, could push the correct button more than 50% of the time in the long run.
a. Describe what a Type I error would be in this study.
b. Describe what a Type II error would be in this study
Solutions
Expert Solution
We know that the type I error occurs when we reject the null hypothesis when it is true and type II error occurs when we do not reject the null hypothesis when it is not true.
a. Describe what a Type I error would be in this study.
The Type I error for this study occurs when we reject the null hypothesis and conclude that Buzz could push the correct button more than 50% of the time, but actually Buzz push correct button less than or equal to 50% of the time.
b. Describe what a Type II error would be in this study
The Type II error for this study occurs when we do not reject the null hypothesis and conclude that Buzz could push the correct button less than or equal to 50% of the time, but actually Buzz push correct button more than 50% of the time.

A study was conducted to investigate whether or not exercise is
a factor in the overall outlook and positive spirit of Denton
County residents. For the study, 400 Denton County residents were
selected at random from each of the following two categories: those
who exercise on a regular basis and those who do not. For the
purpose of this study, the term “regular exercise” was well defined
for all participants. A total of 800 people completed a brief
telephone survey....

An investigator conducts a study to investigate whether there is
a difference in mean PEF in children with chronic bronchitis as
compared to those without. Data on PEF are collected and summarized
below. Based on the data, is there statistical evidence of a lower
mean PEF in children with chronic bronchitis as compared to those
without? Run the appropriate test at α=0.05. Make sure to 1. give
the null and alternative hypotheses, 2. calculate the test
statistic, and 3. give...

who are not vaccinated and are not diseased. Round your answer to
one decimal place.
Step 4 of 8: Find the value of the test statistic. Round your

A study was conducted to investigate whether a new diet lowers
cholesterol. The researchers took a random sample of 100 subjects
with high cholesterol and measured the cholesterol levels for each.
Then each subject began the new diet as instructed. After six
months, the subjects' cholesterol levels were measured again. The
differences in cholesterol level, calculated as After - Before,
follow an approximately normal distribution. Suppose a 99%
confidence interval for the mean cholesterol difference is (-13.89,
-7.66). Which of...

In a study to investigate whether vitamin C is an effective
treatment for colds, volunteers who caught a cold after having been
exposed to various cold viruses are assigned at random to one of
two groups. The 10 volunteers in the experimental group were given
tablets containing 1 gram of vitamin C to be taken four times a
day. The 12 volunteers in the control group were given placebo
tablets. The length of time (in days) the cold lasted for...

Examine the following abstract:
“In this study, we investigate the behavior of new nano ZrO2 and
Al2O3-13 wt.% TiO2 thermal sprayed coatings on commercially pure
(cp)-Ti (grade 4) and titanium alloy substrates. Friction and wear
tests against Al2O3 balls showed that the wear resistance of
Al2O3-13 wt.% TiO2 is better than that ZrO2 coating. Both plasma
sprayings have similar abrasive wear behavior; however, the average
friction coefficient is higher for alumina-titania coating.
Electrochemical tests, open circuit potential monitoring and
potentiodynamic...
