Answer:

H0 : μ = 60 and H1 : μ ≠ 60

Explanation:

H0 : μ = 60 and H1 : μ ≠ 60

Where ;

H0 = the null hypothesis

μ = mean value

H1 = alternative hypothesis

The null hypothesis is our initial assumption, which is the claim that the average number of tissue used during the course of a cold is 60.

The alternative hypothesis will look to negate the null hypothesis, which is to establish that the mean number of tissues used during the course of a cold is not 60, meaning it could be less or more.

liberstina [14]

Answer: International regime

Explanation: The concept was first introduced to international relations by John Ruggie in 1975 but the most widely known definition was given by krasner.

He defined it as a ‘set of implicit or explicit principles, norms, rules, and decision-making procedures around which actors' expectations converge’ in 1983. It was further explained that although regimes include formal treaties and national law, they also rely on informal norms and networks to develop and enforce standard behavior in an area of global policy.

zepelin [54]

The United States House of Representatives.

If no candidate receives the requisite number of votes in the electoral college, then the United States House of Representatives votes and decides who should be President.

The general thinking is that the House is the most representative of the American people and is therefore charged with expediently electing a President.

Inessa05 [86]

Answer: "Up close, she is able to see the painting's details most clearly because her lens focuses light intensely onto her blind spot."

This statement above DOES NOT identify the correct structure were light is focused so we can see clearly.

Explanation: "up close" means to be closer to an image so that you can view it clearly.

The blind spot of the eye is a small part of the optic nerve, which is the visual field of each eye where there are no photoreceptors (rods or cones), and therefore images are not formed in this portion of the eye. When light falls in this portion of the eye, images won't be formed, because the photoreceptors that forms the image for the brain to interpret are not present in that portion.

For example, after being exposed to a bright light, we find it difficult to detect images immediately, because the retina has adjusted for light to fall on the blind spot.

The statement in that paragraph is wrong because her eyes can't detect any image that fall on the blind spot, so therefore the brain will not have any image to interpret, which makes it impossible for her to see clearly

spin [16.1K]

Answer:

The correct answer is: a) neuroticism

Explanation:

The Big Five Personality Traits include: openness (to experience), conscientiousness, extroversion, agreeableness and neuroticism.

The last one - neuroticism - is related to emotional stability/instability and refers to the experience of negative emotions such as depression, anger or anxiety and is associated to low tolerance to stress. Those who score high in this personality trait are usually emotionally reactive and negative emotions are persistent in their daily moods.

Sudie's description refers to an unemotional, even-tempered person, which represents the opposite to the trait of neuroticism.
