Answer:
The number of chocolate made donuts is 40 more than cream filed donuts
Step-by-step explanation:
Given as :
The number of chocolate donuts made = 48
The number of chocolate donuts is 6 times the number of cream filled donuts
So, Let the number of cream filled donuts = x
So, number of chocolate donuts made =
∴
= 48
Or, x =
= 8
So, the number of cream filled donuts = 8
Now ,
The number of chocolate donuts made - the number of cream filled donuts = 48 - 8 = 40
So , The number of chocolate made donuts is 40 more than cream filed donuts Answer
Answer:
(364.595 ; 391.405)
Step-by-step explanation:
Given the sample data:
406, 385, 389, 383, 352, 379, 388, 343, 368, 387
Using calculator :
Sample mean, xbar = 378
Standard deviation, s = 18.74
Confidence interval :
Xbar ± Margin of error
Margin of Error = Tcritical * s/√n
TCritical at df = 24 ; 0.05 = 2.262
Margin of Error = 2.262 * 18.74/√10 = 13.405
Lower boundary = (378 - 13.405) = 364.595
Upper boundary = (378 + 13.405) = 391.405
(364.595 ; 391.405)
