Answer:
A 95% confidence interval estimate of the population mean (average) daily balance of all the checking accounts is $274.32 to $331.68
Step-by-step explanation:
Consider the provided information.
A random sample of 21 checking accounts at the bank are chosen,
That means n=21
df = n-1
df = 21-1=20
We need to Construct and interpret a 95% confidence interval.
Determine t critical value for 95% confidence interval.
0.95=1-α
α=0.05
The sample size is small and it is a two tailed test.
From the t value table confidence interval is 2.086
An average daily balance is $303 and a standard deviation of $63.
Substitute the respective values.
A 95% confidence interval estimate of the population mean (average) daily balance of all the checking accounts is $274.32 to $331.68
Answer: then y should equal 1
Step-by-step explanation: because 4 is half of 8 and 1 is half of 2
Q= Analysts determined that a baseball team had a 25% chance of winning its next game. Which simulation could you use to answer questions about winning the game?
Answer:
<u>For this question, there is a 75% chance of loosing.</u>
<h3><em>
<u>In a similar question .........</u></em></h3>
Q= Analysts determined that a basketball team had a 50% chance of winning its next game. Which simulation could you use to answer questions about winning the game?
A<u>= the team has 50% probilty of suscseeding</u>
<u>So we should use a simulation that also has the same posiblities.
</u>
<u>
so flipping a coin can be used in this situaouion </u>
<u> as it has 2 ends each with probability 1/2. Therefore in this question answer is 50 % </u>

10 red, 6 yellow, 24 blue, 8 white....total of 48 balloons
part to whole (blue) = 24/48 reduces to 1/2 or 1:2 or 1 to 2
3/3 (3 over 3 or 3 divided by 3) is the expression. Each person should get one apple. 3/3 = 4/4 = 9/9 <- these are equal because they all solve to equal 1.
