A New York Timesarticle published on April 24, 2007, reported the research of Dr. Giorgio Vallortigara, a neuroscientist at the University of Trieste, Italy, and his colleagues. In this study, the researchers investigated whether a dog's tail wags in a preferred direction in response to positive as opposed to negative stimuli. The researchers answered this question by recruiting 30 dogs that were family pets. Filming the dog's tail from above, they allowed each dog to view (through a slat in its cage) its owner, an unfamiliar human, a cat (positive stimuli), and an unfamiliar, dominant dog (a negative stimulus). Would it be appropriate for the researchers to use a parametric hypothesis test

Answers

Answer 1

Answer: A dog's tail will wag differently in response to positive stimuli and to negative stimuli.

Explanation:

Dogs wag their tail for various reasons. Most times it is not just done when the are happy but also when they aren't. Dogs wag their tail to convey various messages, but what is very obvious is how it's wagged when they are happy seeing their owners. When a dog is relaxed, the tail is wagged gently, and in most cases a reaction to objects that come in contact with them.

A dog's tail is not wagged only to either positive or negative stimuli but rather to both of them.

True or false China and the Soviet Union were allied against the US.

Answers

I think it WAS true but didn't they stop being allies?

good luck its a 50/50 chance:,) sorry

Answer:

Full diplomatic relations between both the US and the USSR were established in 1933, late due to the countries' mutual hostility. During World War II, both the USSR and the United States were briefly allies.

In 1950, Mao and Stalin safeguarded the national interests of China and the Soviet Union with the Treaty of Friendship, and Alliance and Mutual Assistance. The treaty improved the two country's geopolitical relationship on political, military and economic levels. Stalin's largesse to Mao included a loan for $300 million; military aid, should Japan attack the PRC; the transfer of the Chinese Eastern Railway in Manchuria, Port Arthur and Dalian to Chinese control. In return, the PRC recognized the independence of the Mongolian People's Republic.

Despite the favourable terms, the treaty of socialist friendship included the PRC to the geopolitical hegemony of the USSR, but unlike the governments of the Soviet satellite states in Eastern Europe, the USSR did not control Mao's government. In six years, the great differences between the Soviet and the Chinese interpretations and applications of Marxism–Leninism voided the Sino-Soviet Treaty of Friendship.

In 1958, guided by Soviet economists, the PRC applied the USSR's model of planned economy, which gave first priority to the development of heavy industry, and second priority to the production of consumer goods. Later, ignoring the guidance of technical advisors, Mao launched the Great Leap Forward to transform agrarian China into an industrialized country with disastrous results for people and land. Mao's unrealistic goals for agricultural production went unfulfilled because of poor planning and realization, which aggravated rural starvation and increased the number of deaths caused by the Great Chinese Famine, which resulted from three years of drought and poor weather.
