Which of the following accurately describes the expected frequencies for a chi-square test?

The maximum likelihood estimate under the null hypothesis gives the best estimate for expected frequencies.


How would you determine the expected frequencies for a chi-square goodness of fit test?

You first decide on a null hypothesis. Expected frequencies are calculated on the basis of the null hypothesis, that is, assuming that the null hypothesis is true.


What is the term for the distance between two sound frequencies or pitches?

The term for the distance between two sound frequencies or pitches is called "interval."


Are fundamental frequencies and overtones also called resonance frequencies?

No, fundamental frequencies and overtones are not typically referred to as resonance frequencies. Resonance frequencies are specific frequencies at which an object naturally vibrates or oscillates when subjected to external forces. Fundamental frequencies are the lowest frequency at which an object can vibrate, while overtones are multiples of the fundamental frequency.


What do you mean by expected frequencies in chi square test?

Expected frequencies are used in a chi-squared "goodness-of-fit" test. there is a hypothesis that is being tested and, under that hypothesis, the random variable would have a certain distribution. The expected frequency for a "cell" is the number of observations that you would expect to find in that cell if the hypothesis were true.


How to solve a Hardy-Weinberg problem?

To solve a Hardy-Weinberg problem, you need to use the formula p2 2pq q2 1, where p and q represent the frequencies of two alleles in a population. First, determine the allele frequencies using the given information. Then, use the formula to calculate the expected genotype frequencies. Compare the expected and observed genotype frequencies to determine if the population is in Hardy-Weinberg equilibrium.

What is the general term for activities that are expected to yield a profit?

The general term for activities that are expected to yield a profit is "business activities." These activities encompass various operations, including production, sales, and services, aimed at generating revenue and enhancing profitability. In a broader sense, they can also be referred to as "economic activities."


Are sound waves with frequencies higher than 20 000 Hz referred to as subsonic waves?

No, sound waves with frequencies higher than 20,000 Hz are referred to as ultrasonic waves, not subsonic waves. Subsonic waves are sound waves with frequencies lower than 20 Hz.


Where did the term Underdog originate?

The term "underdog" originated in the context of dogfighting in the 19th century. It referred to the dog that was expected to lose the fight, as opposed to the "top dog," which was anticipated to win. Over time, the term evolved to describe any individual or team that is expected to be at a disadvantage in a competition or struggle, symbolizing resilience and the potential for surprising success against the odds.


If the chi-square is very large what does it mean?

The null hypothesis in a chi-square goodness-of-fit test states that the sample of observed frequencies supports the claim about the expected frequencies. So the bigger the the calculated chi-square value is, the more likely the sample does not conform the expected frequencies, and therefore you would reject the null hypothesis. So the short answer is, REJECT!
