How Fluent a Winery Sounds, Math Problem Example

There is no evidence from the data which states that the sequence of the glasses influenced the data which had been derived from the volunteers. The winery’s name may affect the perception of the wine (Mantonakis 3).

Eight of the dollar bills in a collection of fifty dollar bills have heroin on them. The proportion of dollar bills which possess heroin would be 8/ 50 or 16/ 100. This would be a sixteen percent probability that the dollar bills would have heroin on them.

The answer for the range of the 95% confidence interval is: 8 ± 0.4, 7.6 < 95% < 8.4.

Eight of the bills have heroin on them and there are fifty dollar bills which yields a proportion of 7: 50. The probability is 16%.

The 95% confidence interval would be 100%- 5% = 5%. This implies that the number 6280 ± 314. The 95% confidence interval is 6176< 95% < 6594.

The average number of daily births is calculated by the following formula: Number of births divided by the number of days. 1118/ 7 = 156.7. This is the average number of daily births. The weekend birth rate would be calculated by: 260/ 2 = 130. Yes, the average number of births is less on weekends than weekdays. The alternate hypothesis would be the birth rates are different on weekends. The null hypothesis would be the birth rates are not different on weekends.

The 5% level implies that there can be a 5% deviation from the mean. This means than in order to fulfill the requisites of the 1: 2: 1 ratio, the proportions would be required to be 10: 21: 9.5. The 5% is exceeded by the white flowered offspring, who manifested a 10% difference.

The results continue to differ. In multiplying the total number of flowers by 100, we would get 1000 red, 2100 pink and 900 white flowered snapdragons. The required ratio in order to fulfill the 1: 2: 1 ration with a 5% level would be required to be 1000: 2100: 950.

The proportions in the two tests did not differ. The required ratio is still 1: 2: 1.
