When students leave out a digit when entering an expression into their calculator some students start all over and others use the insert function on their calculator to insert the missing digit. A manufacturer of graphing calculators thinks that 40% of Statistics students know how to use the "insert" feature on their calculator. To investigate, they select a random sample of 150 statistics students and learn that 45 know how to use the insert function on their calculator.

Transcribed Image Text:When students leave out a digit when entering an expression into their calculator some students start all over and others use the
insert function on their calculator to insert the missing digit. A manufacturer of graphing calculators thinks that 40% of
Statistics students know how to use the "insert" feature on their calculator. To investigate, they select a random sample of 150
statistics students and learn that 45 know how to use the insert function on their calculator.
Do the data provide convincing evidence at the a = 0.01 level that fewer than 40% of statistics students know how to use the
insert function on their calculator?
