Question

A theory predicts that the mean age of stars within a particular type of star cluster is 3.3 billion years, with a standard deviation of .4 billion years. (Their ages are approximately normally distributed.) You think the mean age is actually greater, and that this would lend support to an alternative theory about how the clusters were formed. You use a computer to randomly select the coordinates of 50 stars from the catalog of known stars of the type you're studying and you estimate their ages. You find that the mean age of stars in your sample is 3.4 billion years.

Answer 1

Answer:

The answer to this question can be defined as follows:

Step-by-step explanation:

Please find the complete question in the attached file.

Lets $\mu$ in trillions of years be the maximum likelihood age of galaxies in a certain type of star cluster.

Calculating the Hypotheses:

Null hypothesis value:$H_o : \mu = 3.3$

Alternative hypothesis value: $H_A : \mu > 3.3$
