24 A kitchen has space for a fridge.
(a) The width, \(w\), of the space is 70 cm, correct to the nearest centimetre.
Complete the error interval for the width, \(w\).
\[\ldots\ldots\ldots\ldots \leqslant w < \ldots\ldots\ldots\ldots\][2]
(b) A fridge is advertised as having a width of 69.5 cm, correct to 1 decimal place.
Show that this fridge may not fit in the space. [2]

| Accept any correctly matched pair of values in which space < fridge from these ranges \(69.5 \leqslant\) space \(< 69.55\) and \(69.5 <\) fridge \(< 69.55\) e.g. s = 69.5 and f = 69.54 | 2 | B1 for one value for space or fridge where \(69.5 \leqslant\) space \(< 69.55\) e.g s = 69.5 or \(69.5 <\) fridge \(< 69.55\) e.g. f = 69.51 | Error interval (e.g. ...\(\leqslant\) space < ...) alone scores 0 Only mark candidate’s chosen value(s) Measurements used must be clearly associated with space and/or fridge Space < fridge does not need to be stated For B1 if one or multiple values for fridge/space seen and no clear choice all must be in correct ranges |
