Answer:
p value is 0.1343
Step-by-step explanation:
Null: u>= 442
Alternative: u < 442
Using the formula for z score:
(x - u)/sd/√n
Where x is 438, u = 442 sd can be determined from the variance = √variance =√576 = 24 and n = 44
z score = 438-442 / (24/√44)
z score = -4/(24/6.6332)
z = -4/3.6182
z =-1.1055
Now let's find the p value at 0.1 significance level using a z score of -1.1055, using a p value calculator, p value is 0.1343 which greatest than 0.1 meaning the day is not sufficient enough to conclude that the machine is underfilling the bags.
Answer:
$38.40
Step-by-step explanation:
9.
( 5 / 8 ) * ( 2 / 3 ) = 10 / 24 = 5 / 12 A ;
10.
( 11 / 12 ) ÷ ( 5 / 7 ) = ( 11 / 12 ) * ( 7 / 5 ) = 77 / 60 = 1 17 / 60 D ;
11.
3 / 8 B;
12.
2 5 / 8 = 21 / 8 ; the reciprocical of 21 / 8 is 8 / 21 C ;
13.
$12.50 * 34.5 =$ 431.25 C ;
