Test the claim that the proportion of people who own cats is significantly different than \( 10 \% \) at the 0.2 significance level. The null and alternative hypothesis would be: \( H_{0}: p=0.1 \quad H_{0}: p=0.1 \quad H_{0}: \mu=0.1 \quad H_{0}: \mu=0.1 \quad H_{0}: p=0.1 \quad H_{0}: \mu=0.1 \) \( H_{1}: p \neq 0.1 \quad H_{1}: p<0.1 \quad H_{1}: \mu \neq 0.1 \quad H_{1}: \mu>0.1 \quad H_{1}: p>0.1 H_{1}: \mu<0.1 \) The test is: right-tailed left-tailed two-tailed Based on a sample of 700 people, \( 8 \% \) owned cats The test statistic is: \( -\quad \) This is not a decimal or integer value. (to 4 decimal places) The p-value is:

Select all of the possible null hypotheses from the list below. \( p=0.37 \) \( p>0.84 \) \( p<0.42 \) \( p \neq 0.10 \)

Bila diberikan sebuah sebaran normal dengan \( \mu=40 \) dan \( \sigma=6 \), hitunglah: a. Luas daerah di bawah 32 b. Luas daerah di atas 27 c. Luas daerah di antara 42 dan 51 d. Nilai x yang luas daerah di bawahnya \( 45 \% \) e. Nilai \( x \) yang luas daerah di atasnya \( 13 \% \)
