Test the claim that the proportion of men who own cats is smaller than 70% at the
005 significance level.
The null and alternative hypothesis would be:
Ho u0.7 H: p 0.7 Ho:p = 0.7 Ho p 0.7 Ho: u 0.7
H 0.7 H1 :p 0.7 H p 0.7 H:p > 0.7 H1 < 0.7
Ho: u0.7
H 0.7
The test is:
right-tailed two-tailed left-tailed
Based on a sample of 70 people, 61% owned cats
* (to 2 decimals)
The test statistic is:
|* (to 2 decimals)
The critical value is:
Based on this we:

Transcribed Image Text:In a certain school district, it was observed that 25% of the students in the element
schools were classified as only children (no siblings). However, in the special
program for talented and gifted children, 100 out of 349 students are only children.
The school district administrators want to know if the proportion of only children in
the special program is significantly different from the proportion for the school
district. Test at the a =
