Random sampling research has been conducted for dying quality of light bulbs produced by a firm. Simple sample of 20 bulbs from a batch produce as been served in aver the testing it has turned out that 10% of them do not withstand the necessary hours of lightening At significance level a 0.05 test the hypothesis whether the quality of light bulbs produced meets the standard according which the proportion of nonstandard bulbs should not exceed 2% of all produced. Answer A) Ho is confirmed, thus at a 0,05 the quality of light bulbs produced meets the standard since the proportion of nonstandard bulbs is smaller than allowed. Answer B) Hi is confirmed, thus at a 0,05 the quality of light bulbs produced does not meet the standard since the proportion of nonstandard bulbs is larger than allowed. Answer C) Hi is confirmed, thus at a-0,05 the quality of light bulbs produced meets the standard since there is no significant difference between the proportion of nonstandard bulbs and standard. Answer D) H is rejected, thus at a 0,05 the quality of light bulbs produced does not meet the standard since the proportion of nonstandard bulbs is larger than allowed. Answer E) Ho is confirmed, thus at a-0,05 the quality of light bulbs produced meets the standard since the proportion of nonstandard bulbs is smaller than allowed.
