A z-test is a statistical test which compares a test statistic - the z-score - which is based on data with the standard normal distribution. If used appropriately (very often it isn't) it will indicate the probability, under a null hypothesis, of observing an outcome at least as extreme.

A simple z is a letter of the alphabet. In algebra it is used to denote variables; in coordinate geometry it is usually used to denote the third orthogonal direction for the coordinate space.

There is not enough information to answer the question sensibly. Is it implied that out of 200 students not one knew the answer to any one of the seven questions? And that all pupils had to make random choices for each question? Is that at all credible?

Yes.

For English speaking people, they are in alphabetical order.

The median.

Allowing numbers that start with zero, the answer is

6!/(2!*2!) = 720/(2*2) = 180

Standardising the observation ensures that the mean is 0 and the standard error is 1. Otherwise the plot could be located anywhere and be concentrated or spread out.

Consider the set (1, 2, 3, 4, 5) There are five elements in that set and they total 15. Fifteen divided by five gives us the mean, which is 3.

0.5, if the coin is fair.

The median is the value that is in 'the middle'. That is, half the values fall below it, half above it. There are a total of 3 + 5 + 6 = 14 sample values. There is no 'middle' value exactly since there are an even number of values.

Both the 7th and the 8th largest value are 100 g. Their average is 100 g. Therefore, the median of this sample is 100 g.

Yes, since fundamental frequency is based on the standing wave that forms, by changing the amount of liquid you change the length of the medium the standing wave is in, thus the perceived frequency.

What is the routine or trime table for BSc.[H] , part-1 exam, 2009 under Calcutta University? I am a student of Botany honours under the same university with general courses, Chemistry and Zoology.

It has been recently discovered (Aug 2017), by researchers at the University of New South Wales, that a 3,700 year old Babylonian tablet, known as Plimpton 332, contained tables of trigonometric ratios. The tablet is approx 1500 years older than the Greek astronomer Hipparchus who has long been regarded as the father of trigonometry. So, with that one discovery, the history of trigonometry has become less brief and its origins have been shifted from Europe to the Middle East. It is not yet clear what else the Babylonians achieved in the intervening 1500 years.

Actually, a survey is means of getting a sample. Whether you send a questionaire, ask people's opinion or have people give opinions over the interpet, your dataset is a sample or subset of the population.

Multiply meters per second by 3600 to get meters per hour (60*60 = 3600 seconds in one hour)
