Four cement bags labelled, "5 kg", were delivered to a customer. The cu
snmm y- (4z 4tj(5k qs9mxuxy2stomer measured e
x( sk5m (q-zmx4 29myys4utnjach bag to check their weights and recorded the following:
4.92,4.95,5.02,4.95
1.1.Find the mean of the customer's measurements.
If we calculate the mean of the measurements, we get μ=
.
1.2.Calculate the percentage error between the mean and the stated,
approximate weight of 5 kg.
Using the percentage error formula ϵ=
%.
2.1.correct to the nearest integer;
The number=

2.2.in the form a×10$^k$, where 1≤a<10 and k∈Z.
The number=
×10$^1$.
