I am planning to run a study to examine the relationship between marital satisfaction and financial security. I expect to find a correlation of about .58.(a)Calculate the effect size for these results (to 2 decimals). Always report the effect size as positive.

(b)What total sample size should I use to ensure 80% power?

(c)Is this an appropriate sample size to use for the planned replication?

Yes, this sample size will provide adequate power.No, this sample size won't provide enough power.

Each of 62 cat owners and 62 bird owners were asked whether they preferred action movies or drama movies. Fewer cat owners watched drama movies than action movies, while bird owners displayed no movie preference, X(1)=5.2.(a)Calculate the effect size for these results (to 2 decimals). Always report the effect size as positive.

(b)What total sample size should I use in a replication of this study to have 80% power?

(c)How many participants will be in each condition?

(d)Is this an appropriate sample size to use for the planned replication?

Yes, this sample size will provide adequate power.

Please explain why so I can try to grasp how to get the means, effect size, ect.

Thank you
