We'll suppose you set a significance level of \( 10 \% \). Then you fandomly select 42 adults in town and ask them how often they eat in a restaurant. The number who say "at least once a week". is 17 . Now calculate the sample proportion: \( \widehat{\mathbf{p}}= \) Round to 3 decimal places-i) If the null hypothesis is true, the probability of getting a sample proportion that hypothesis is 0.086 . What should you do with \( \mathrm{H}_{0} \) ? Do not reject null hypothesis

Mean and Standard Deviation scept Rate \( \frac{\mathbf{n}:}{(5+5+8+3+12+10+18+15+12+16+20+18+20+20+24+26+25+28+25+30} \) Idard Deviation:

\( 1 \leqslant \quad \) Find the value of \( z_{\alpha} \) \( z_{0.48} \) \( z_{0.48}=\square \) (Round to two decimal places as needed.)

QUESTÃO 15- Uma pesquisa foi realizada com 100 alunos sobre sua preferência por frutas. Os resultados foram: \( 40 \% \) preferem maçã, 30\% preferem banana e o restante preferem laranja. Quantos alunos preferem laranja?

Grad rate r - 865 /square root \( 865 * 865=865 / 865=1 \) Accept rate \( \mathrm{r}-252.55 \) / square root \( 200 * 2000=252.55 / 632.46=0.399 \) Q2e. Explain the direction and strength of the relationship based on the \( r \). [1 point total: 0.5 for strength, 0.5 for direction] Grad rate has a strong/ positive relationship Acceptance rate has a weak/ postive relationship Q2f. What is the proportion of variance shared between the two variables? (That is, how much of variance in one variable can be predicted by the variance in the other variable?) (Do not round du the calculation, the final result as the percentage should be to the hundredth [2nd decimal]) [1 point total: -0.5 if the process is correct but the answer is wrong]
