Answer:
29.03g
Step-by-step explanation:
The total mass of the jar and marbles combined is 1.281kg, or 1281g. Subtract the mass of the jar from this to find the total mass of the marbles (1281g - 236g = 1045g). Then, divide this number by 36 to find the mass of each marble (1045g / 36 = 29.03g).
Confidence interval is given by the formula
x ⁺/₋ z* ( σ/ (√n) )
Where:
x = the sample mean = 130
z* = the z-value for 90% confidence = 1.645
σ = standard deviaton = 7
n = sample size = 145
Substituting these values into the formula gives:
130 ⁺/₋
130 ⁺/₋ 0.956
So the interval is in between (130 - 0.956) and (130 + 0.956)
