Answer:
Step-by-step explanation:
Alright, lets get started.
The probability that an event will occur is 2/3.
Means out of 3 times, 2 times that event will occur.
Please refer the pie chart for this, blue is the color which represents event to be occur and orange is not to be occur.
We can see, blue part is much more than orange part.
means the likelihood of event occuring is LIKELY. : Answer
Hope it will help :)
Answer:
The value of y is
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem the line passes through the origin
therefore
Is a proportional variation
Find the value of k
with the point
The equation is equal to
so
For
substitute
Answer:
Option a) Type I error would occur if we reject null hypothesis and conclude that the average amount is greater than $3,200 when in fact the average amount is $3,200 or less.
Step-by-step explanation:
We are given the following information in the question:
where μ is the average amount of money in a savings account for a person aged 30 to 40.
Type I error:
Thus, in the above hypothesis type error will occur when we reject the null hypothesis even when it is true.
Option a) Type I error would occur if we reject null hypothesis and conclude that the average amount is greater than $3,200 when in fact the average amount is $3,200 or less.
