Major league baseball team plays 162 game schedule so far graces favorite team won 11 games and lost 7 games if graces team wins

Vinil7 [7]

Answer:

Graces expect her Favorite team can win 99 games.

Step-by-step explanation:

Total games needs to be played = 162

So far graces favorite team won 11 games and lost 7 games

Games Won = 11

Games lost = 7

Total games played till now = Games Won + Games Lost = 11 +7 =18

Now we will find the winning percentage of the team.

Winning percentage can be calculated by dividing Games won with total games played till now and the multiplied with 100

Winning Percentage = $\frac{11}{18}\times100=61.11\%$

We need to find Total games team can win at same rate.

Games team can win can be calculated by multiplying Total games needs to be played this season with Winning Percentage.

Games team can win = $\frac{61.11}{100}\times 162 = 98.99 \approx 99$

Hence Graces can expect her favorite can win approximately 99 games.

A student randomly draws a card from a standard deck and checks to see if it is his favorite suit he then returned to card to th

tensa zangetsu [6.8K]

Answer:

The binomial probability formula can not be used for this experiment because it does not state the number of times he expects to draw his favorite suit.

Step-by-step explanation:

The binomial probability formula is expressed as follows:

P (k success in n trials) = $\left \{ {{n \atop k} \right.$ $p^{k}$ $q^{n-k}$

n = number of trials, k = number of successes, n-k = number of failures, p = probability of success in one trial and q = 1 - p = probability of failure in one trial.

In the given problem, all of the variables are known except for 'k', the amount of times that the student predicts he will draw his favorite suit.

Several years ago, 50% of parents who had children in grades K-12 were satisfied with the quality of education the students r

galina1969 [7]

Answer:

The 95% confidence interval for the proportion of parents that are satisfied with their children's education is (0.4118, 0.4618). 0.5 is not part of the confidence interval, so this represents evidence that parents' attitudes toward the quality of education have changed.

Step-by-step explanation:

We have to see if 50% = 0.5 is part of the confidence interval.

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$ .

For this problem, we have that:

$n = 1095, \pi = \frac{478}{1095} = 0.4365$

95% confidence level

So $\alpha = 0.05$ , z is the value of Z that has a pvalue of $1 - \frac{0.05}{2} = 0.975$ , so $Z = 1.96$ .

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.4365 - 1.96\sqrt{\frac{0.4365*0.5635}{1095}} = 0.4118$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.4365 + 1.96\sqrt{\frac{0.4365*0.5635}{1095}} = 0.4612$

The 95% confidence interval for the proportion of parents that are satisfied with their children's education is (0.4118, 0.4618). 0.5 is not part of the confidence interval, so this represents evidence that parents' attitudes toward the quality of education have changed.
