A group of scientists discovered a small creature at the bottom of the ocean that they called a "piknit". When this interesting creature dies, it explodes itself into a number of baby piknits called gogles. The scientists randomly selected 20 piknits from the sea-floor and measured their respective weights in grams. After the piknits died they counted the number of gogles that each piknit produced. They wanted to know if the weight of the piknits can be used to predict the number of gogles.What are the appropriate null and alternative hypotheses?Group of answer choicesH0: There is no linear relationship between the weight of piknits and the number of goglesHa: There is a negative linear relationship between the weight of piknits and the number of goglesH0: Weight of piknits is a useful predictor for the number of goglesHa: Weight of piknits is not a useful predictor for the number of goglesH0: There is a linear relationship between the weight of piknits and the number of goglesHa: There is no linear relationship between the weight of piknits and the number of goglesH0: There is no linear relationship between the weight of piknits and the number of goglesHa: There is a linear relationship between the weight of piknits and the number of gogles

The appropriate null and alternative hypothesis for calculating number of gogles is H0 : No linear relation H1 : there is a relation

Correlation is a statistical measure that expresses the extent to which two variables are linearly related (meaning they change together at a constant rate).

It's a common tool for describing simple relationships without making a statement about cause and effect.

According to the question,

A group of scientist randomly selected 20 piknits from the sea-floor and measured their respective weights in grams.

Also, They wanted to know if the weight of the piknits can be used to predict the number of gogles.

From the given information,

Null hypothesis : H0 : There is no linear relationship between the weight of piknits and the number of gogles

Alternative hypothesis : Ha: There is a linear relationship between the weight of piknits and the number of gogles

Option 4 is correct about null and alternative hypothesis
