In a study of the impact of smoking on birth weight, researchers analyze birth weights (in grams) for babies born to 189 women w
kompoz [17]

Answer:

c. Smoking is associated with lower birth weights. When smokers are compared to nonsmokers, we are 95% confident that the mean weight of babies born to nonsmokers will be between 76.5 grams to 486.9 grams more than the mean birth weight of babies born to smokers.

Step-by-step explanation:

The difference in mean birth weights (nonsmokers minus smokers) is 281.7 grams with a margin of error of 205.2 grams with 95% confidence.

Then, we know that the 95% confidence interval is (76.5, 486.9)

LL=M-MOE=281.7-205.2=76.5\\\\UL=M-MOE=281.7+205.2=486.9

<em>a. We are 95% confident that smoking causes lower birth weights by an average of between 76.5 grams to 486.9 grams.</em>

False, it interprets the confidence interval as a probability for individual cases. The confidence interval is a range for the population mean.

<em>b. There is a 95% chance that if a woman smokes during pregnancy her baby will weigh between 76.5 grams to 486.9 grams less than if she did not smoke.</em>

False, it interprets the confidence interval as a probability for individual cases. The confidence interval is a range for the population mean.

<em>c. Smoking is associated with lower birth weights. When smokers are compared to nonsmokers, we are 95% confident that the mean weight of babies born to nonsmokers will be between 76.5 grams to 486.9 grams more than the mean birth weight of babies born to smokers.</em>

True.

<em>d. With such a large margin of error, this study does not suggest that there is a difference in mean birth weights when we compare smokers to nonsmokers.</em>

There is enough evidence, as the lower bound of the confidence is positive. This means that there is only a probability of 0.05/2=0.025 that the true mean weight difference is smaller than 76.5 grams.

Randomly picking a green card from a standard deck of playing cards. 3. randomly picking a red card from a standard deck of play
Akimi4 [234]
<span>Formula: probability = number of positive outputs / total number of possible events

Randomly picking a green card from a standard deck of playing cards.

A standard deck of playing cards does not have green cards, so the probability is 0.

3. randomly picking a red card from a standard deck of playing cards

Half of the cards from a standard deck of playing cards are red, so the probability is 0.5.

4. picking a number less than 15 from a jar with papers labeled from 1 to 12

All the papers have a number less than 15, so the probability of picking a number less than 15 is 1.

5. picking a number that is divisible by 5 from a jar with papers labeled from 1 to 12

The numbers divisible by 5 from 1 to 12 are 5 and 10, so there are two positive outputs from a total of 12 possible events and the probabily of picking a number that is divisible by 5 is 2 / 12 = 1/6.

Answr: 1/6.

use the complement to find each probability. (example 3)

8. what is the probability of not rolling a 5 on a standard number cube?


The probability of rolling a 5 is 1 out of 6 = 1/6

The complement is 1 - 1/6 = 5/6.

Therefore, the probability of not rolling a 5 is 5/6.

9. a spinner has 3 equal sections that are red, white, and blue. what is the probability of not landing on blue? 1

The probability of landing on blue is 1 / 3. The complement is 1 - 1/3 = 2/3.

Therefore, the probability of not landing on blue is 2/3.

2. describe an event that has a probability of 0% and an event that has a probability of 100%. essential question check-in ??

Rolling a 7 with a standard cube has probability 0%.

Rolling a number different from 7 from a standard cube has a probability of 100%.


10. a spinner has 5 equal sections marked 1 through 5. what is the probability of not landing on 4?

Each section has a probability of 1/5.

So not landing on 4 has a probability of 1 - 1/5 = 4/5.

11. there are 4 queens in a standard deck of 52 cards. you pick one card at random. what is the probability of not picking a queen?

Picking a queen has probability of 4/52 = 1/13.

The complement is 1 - 1/13 = 12/13.

Therefore, the probability of not picking a queen is 12/13.
