Use the data to create a scatter plot\ forks: 2,4,6,8,10,12 spoons: 10,6,4,1,0,2
1 answer:
Answer:
The resulting scatter plot is attached below :
To plot the required scatter plot :
We first take forks on the x - axis and the spoons on the y - axis
Now we arrange the given data in the form of x and y coordinates
Hence, the data becomes :
(2, 10)
(4, 6)
(6, 4)
(8, 1)
(10, 0)
(12, 2)
Now, We plot these points on the graph and get the required scatter plot for the given data.

Answer:
95%
Step-by-step explanation:
For a given sample data, the width of the confidence interval would vary directly with the confidence level i.e. more the confidence level, wider will be the confidence interval.
This is because the critical value associated with the confidence level(e.g z value) becomes larger as the confidence level is increased which results in an increased interval.
The confidence interval for a population proportion is given by the formula:
So, for a fixed value of p,q and n, the larger the value of z the wider will be the confidence interval.
Hence 95% confidence interval will be wider than 80% confidence interval.
