Which of these pairs of events are independent?

1 answer:

3 0

B.You reach into a basket and draw a name for a prize, return the name into the basket, and then draw a second time for another prize.

The results of the prizes in the first basket are not related at all to what happens in the second basket. So these two events are independent.

Hope this helps :)

Answer:

The calculated t-value is t=0.47.

Step-by-step explanation:

The question is incomplete:

"Americans typically eat quickly and do not spend time enjoying their meal. A researcher plans to test if those trained in mindfulness will take more time to enjoy their meal (that is, they will spend more time eating than the general population). The general population spends an average of 68 minutes per day combined eating their three meals. The researcher trains a sample of 16 individuals in mindfulness and then collects data on how long they spend eating per day. The sample mean for those trained in mindfulness equals 74; the SS = 150. What is the calculated t-value? Round your answer to two decimal places."

The degrees of freedom are (n-1)=(16-1)=15

The standard deviation is:

$s=\sqrt{\frac{SS}{n-1}}=\sqrt{\frac{150}{16-1}}=\sqrt{10}=3.16$
