</span><span>The projectile initially launched at time t=0, so the initial height is h(0)=2 m</span>
Answer:
a) 66.1 < μ < 82.7
b) 71.9 < μ < 97.7
c) D. No, because the two confidence intervals overlap, we cannot conclude that the two population means are different.
Step-by-step explanation:
Confidence interval is given by the formula
M±t×(
) where
- M is the sample mean
- t is the corresponding t value for 95 confidence level
- s is the sample standard deviation
- N is the sample size
<u>a. Construct a 95% confidence interval estimate of the mean pulse rate for males.</u>
For men:
M=74.4 t=2.262 s=11.6207 N=10 then confidence interval is:
74.4±2.262×(
) ≈ 74.4±8.3
<u>b. Construct a 95% confidence interval estimate of the mean pulse rate for females.</u>
For women:
M=84.8 t=2.262 s=18.0488 N=10 then confidence interval is:
84.8±2.262×(
) ≈ 84.8±12.9
<u>c. Compare the preceding results. Can we conclude that the population means for males and females are different?</u>
Difference of Population means for males and females are not statistically significant, since confidence intervals overlap.

A Bakery Sells Muffins And Bagels. Each Muffin Costs 2.25 And Each Bagel Costs 1.50 . The Bakery Earns 775.50 From The Sale Of Muffins And Bagels On Saturday.
A. Write An Equation In Standard From The Repressents This Situation. (Ax+By=C)
B. If The Barkey Sells 322 Bagels, How Many Muffins Did They Sell?
Answer:
130 muffins
Step-by-step explanation:
Let A be the costs of each Muffin And B be the cost of each Bagel.
Let x be the Muffins and y be the the Bagel.
Given:
So, the equation is written as.
---------(1)
Bakery sells 322 Bagels.
We need to find muffins sell.
Solution:
Bakery sells 322 Bagels that means y = 322
Now, we substitute y value in equation 1.

Solve the above equation for x.




x = 130 muffins
Therefore, the bakery sells 130 muffins.
For the decimal rounded to the nearest tenth, 5 is is greater than numbers 1-4. So 5 rounds the 1.
0.2
0.2 in fraction form is 1/5.
Answer: 1 fl oz is greater than 4 tsps.
Happy to help! :)
