Answer: If the level of confidence is increased without changing the sample size then<em> </em><u><em>The margin of error will decrease because the critical value will decrease. The decreased margin of error will cause the confidence interval to be narrower.</em></u>
where;
<em>Margin of error = Critical value × Standard deviation</em>
<em>Here, it can be duly noted that Margin of error has a positive relation with critical value, i.e </em><u><em>The margin of error will decrease because the critical value will decrease.</em></u>
<u><em>whereas;</em></u>
The confidence interval is <em>the value ± the margin of error.</em>
<em>Therefore, </em><u><em>the decreased margin of error will cause the confidence interval to be narrower.</em></u>
Hello!
You first find out how many objects there are in total
4 + 9 + 3 = 16
Then you find the probability of Liliana picking a orange
Since there are 4 oranges and 16 things to pick she has a 4/16 chance of getting an orange
Next you find the probability of Liliana picking a pear
There are 3 pears and 16 items to pick so she has a 3/16 chance
Then you add them together to find the chance of either happening
4/16 + 3/16 = 7/16
So she has a 7 out of 16 chance of getting an orange or a pear
The answer is 7/16
Hope this helps!
Answer:
One solution
Step-by-step explanation:
0.75 (x + 40) = 0.35 (x + 20) + 0.35 (x + 20)
0.75x + 30 = 0.35x + 7 + 0.35x + 7
0.75x + 30 = 0.7x + 14
0.05x + 30 = 14
0.05x = -16
x = -320
Hope this helps!
