QUESTIONS AND ANSWERS /A+ GUIDE SOLUTION.
Suppose you are given 3 numbers that relate to the number of
people in a sample. The three numbers are 10, 20 and 30. If the
standard deviation is 10, the standard error equals - ANSWER-
5.77
To find the standard deviation, find the mean of the data set ( 10,
20, 30) then calculate in excel. Watch video Bozeman Science
Standard Error
Find the sample standard deviation of 5, 10, 15 and 20. -
ANSWER-6.45
standard deviation - ANSWER-a computed measure of how
much scores vary around the mean score
Type 1 error - ANSWER-Rejecting null hypothesis when it is true
type 11 error - ANSWER-false negative
, Type 1 error criminal - ANSWER-Innocent person is wrongly
convicted
The hypothesis of most interest to the researcher is: - ANSWER-
the alternative hypothesis
p-value - ANSWER-The probability level which forms basis for
deciding if results are statistically significant (not due to
chance).
Variance - ANSWER-the square of the standard deviation
one-tailed test - ANSWER-A hypothesis test in which rejection of
the null hypothesis occurs for values of the test statistic in one
tail of its sampling distribution.
unbiased estimator - ANSWER-a sample statistic which has an
expected value equal to the value of the population parameter
Suppose a population of blue whales is 8000. Researchers are
able to garnish a sample of oceanic movements from 100 blue
whales within the population. Thus,
- researchers do not have a significant sample size
- researchers need a larger population of blue whales
