Melanie buys a skirt that costs 32.00. she pays 10% sales tax. how much does she pay for the dress, with tax

$35.2 dollars

Step-by-step explanation:

You divide 10 by 32.00 and whatever that number equals, you add to 32.00:) Ta da! Hope this helps

0.05

a) Power will remain the same

b) Power will increase

Step-by-step explanation:

Total number of Skittles = 200

Number of orange Skittles = 43

Level of Significance = 0.05

Probability of making a type 1 error is the probability of rejecting the null hypothesis when it is true. The probability of making a type 1 error is the significance level

Therefore type 1 error = 0.05

a) If the observed statistic is 86/100, the power will increase.

The power is the probability of rejecting the null hypothesis when it is false. (i.e not making a type 2 error)

The power depends on sample size, significance level, variability in the response variable, etc.

Since 43/200 is the same as 86/400 in value and the significance level is not said to be changed, the power will remain the same.

b) Power depends on significance level. Therefore, if the significance level is changed from 0.05 to 0.10, the power will increase.
