Answer:
A chi-square goodness-of-fit test shows that the frequencies observed fit well with those that were expected. Hence, the decision was to <u>retain the null hypothesis .</u>
Step-by-step explanation:
A chi-square goodness-of-fit test shows that the frequencies observed fit well with those that were expected then the value of the test statistic is equal to zero.
Then the decision would be to retain the null hypotheses as zero is included in any value of the level of significance applied.
The chi square is a continuous distribution ranging from zero to plus infinity.
False, only living things are made up of cells.

Step-by-step explanation:
Try this solution:
1. for probability of both televisions work:
2. for probability of at least on is defective (it means, the sum = one is defective and two are defective):
- for P(1defective);
- for P(2defective);
totaly for at least one is defective:
