Past experience has indicated that the breaking strength of yarn used in manufacturing drapery material is normally distributed and that σ = 4 psi. a random sample of 10 specimens is tested, and the average breaking strength is found to be 93 psi. find a 95% two-sided confidence interval on the true mean breaking strength. round the answers to 1 decimal place.

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

multiple all that

step-by-step explanation:

27×17

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
