The graph shows the CPI from 2013 to 2020. If a 4 pint carton of milk costs £1.10 in 2020, what calculation do I do to find the price in 2019?

1.10 ÷ 1.044 1.10\div1.044 1 . 1 0 ÷ 1 . 0 4 4

1.10 ÷ 0.956 1.10\div0.956 1 . 1 0 ÷ 0 . 9 5 6

1.10 × 0.956 1.10\times0.956 1 . 1 0 × 0 . 9 5 6

1.10 × 1.044 1.10\times1.044 1 . 1 0 × 1 . 0 4 4

What is the formula used to find a confidence interval?
