Test the hypothesis that the proportion of Elementary School Districts being Anderson has increased from 30%. a) Express the null and alternative hypotheses in symbolic form for this claim. Enter your answer as a decimal. For example, if you have 35%, enter 0.35. Remember to enter a zero in front of the decimal point. However, if you have a percentage that is a multiple of 10, do not include the 0 after the number. For example, if you have 20%, enter 0.2, not 0.20. Ho: Hai Use the following to enter parameters: Proportion: enter p Mean: enter mu Use the following codes to enter the following symbols: enter >= enter <= # enter != b) Find the test statistic. Round to two decimal places. c) What is the p-value? Round to 4 decimals. P = d) Make a decision base on a 0.01 significance level. Do not reject the null Reject the null e) What is the conclusion?

I need help with this problem
Transcribed Image Text:Test the hypothesis that the proportion of Elementary School Districts being Anderson has increased from
30%.
a) Express the null and alternative hypotheses in symbolic form for this claim. Enter your answer as a
decimal. For example, if you have 35%, enter 0.35. Remember to enter a zero in front of the decimal
point. However, if you have a percentage that is a multiple of 10, do not include the 0 after the number.
For example, if you have 20%, enter 0.2, not 0.20.
