Answer:
The odds of the event happening = 7:3
Step-by-step explanation:
Given
Probability of an event happening = 70%
To find the odds of the event happening.
Solution:
Odds of an event happening is the ratio of the probability of the event happening and the probability of the event not happening.
Probability of the event not happening will be =
So, the ratio of the probabilities of event happening and not happening can be given as:
⇒
⇒ [Representing percent in fraction form]
⇒ [Replacing division sign with multiplication sign by taking reciprocal of divisor.]
⇒ [Canceling out the common terms]
⇒ [Reducing fraction to simplest form]
Thus, odds of the event happening is =
Answer:
The Cohen's d effect size is 0.05.
Step-by-step explanation:
The Cohen's d effect size is a numerical value that indicates the standardized difference between two means.
It is provided that the mean time to complete an experimental task reported by the researcher is,
Since the standard deviation of the population is not provided we will use a one-sample <em>t</em> - test to perform the analysis.
The formula of Cohen's d effect size in case of one-sample <em>t</em> - test is:
Compute the value of Cohen's d effect size as follows:
Thus, the Cohen's d effect size is 0.05.
