7 Components are machined to a nominal diameter of 32-65 mm. A samp batch of 400 components gave a mean diameter of 32-66 mm with standard deviation of 0-02 mm. For a production total of 240 components, calculate: (a) the limits between which all the diameters are likely to lie (b) the number of acceptable components if those with diameters le than 32-62 mm or greater than 32-68 mm are rejected.

Urgent help needed

7 Components are machined to a nominal diameter of 32-65 mm. A sample batch of 400 components gave a mean diameter of 32-66 mm with a standard deviation of 0-02 mm. For a production total of 2400 components, calculate: (a) the limits between which all the diameters are likely to lie (b) the number of acceptable components if those with diameters less than 32-62 mm or greater than 32-68 mm are rejected.
