Only about 15% of all people can wiggle their ears. Is this percent higher for millionaires? Of the 352millionaires surveyed, 60 could wiggle their ears. What can be concluded at the a = 0.05 level ofsignificance?a. For this study, we should use z-test for a population proportionb. The null and alternative hypotheses would be:Но: р0.15(please enter a decimal)H1: P(Please enter a decimal)0.15c. The test statistic z1.077X (please show your answer to 3 decimal places.)d. The p-value =0.140X (Please show your answer to 3 decimal places.)e. The p-value is >vf. Based on this, we should fail to rejectofthe null hypothesis.g. Thus, the final conclusion is that ...OThe data suggest the population proportion is not significantly higher than 15% at a = 0.05, sothere is statistically insignificant evidence to conclude that the population proportion ofmillionaires who can wiggle their ears is higher than 15%.O The data suggest the population proportion is not significantly higher than 15% at a = 0.05, sothere is statistically significant evidence to conclude that the population proportion ofmillionaires who can wiggle their ears is equal to 15%.O The data suggest the populaton proportion is significantly higher than 15% at a = 0.05, sothere is statistically significant evidence to conclude that the population proportion ofmillionaires who can wiggle their ears is higher than 15%.ofof

Find the z-score corresponding to the given value and use the z-score to determine whether the value is significantly low or high. Consider a score to be significantly low if its z-score is less than or equal to -2. Consider a z-score to be significantly high if it is greater than or equal to 2. Round the z-score to the nearest tenth if necessary. A body temperature of 96.7° F given that human body temperatures have a mean of 98.20° F and a standard deviation of 0.62°.
