I am struggle with these questions. This is in topic "The idea of a confidence interval" and "Confidence intervals for one sample proportions". Please help me, thank you so much!

Question 7 1 pts Confidence and Precision In a recent study, 1,115 males 25 to 35 years of age were randomly chosen and asked about their exercise habits. Based on the study results, the researchers estimated the mean time that a male 25 to 35 years of age spends exercising with 90%, 95%, and 99% confidence intervals. These were (not necessarily in the same order): (3. 4): (2.5, 4.5): (2. 5): 2 The confidence interval in which you have the most confidence that it captures the population mean u must be: O the 95% confidence interval the 99% confidence interval O the 90% confidence intervalQuestion 5 1 pts Select all that are true. Bias from the sampling process (like using a convince sample) is taken into account in the error for the confidence interval. Bias from natural variation in the population is taken into account in the error for the confidence interval If several samples are taken and a confidence interval for each is created all the confidence intervals will be centered at the same number.Question 6 1 pts Fill in the table. Interval Probability the true value of the Probability the true value of the Confidence Level (C) number population parameter is NOT in |population parameter IS in the the interval. interval. 99% % % NO % % 92% % 9% % % 16% % % 80% 6 75% % % Which interval is the widest? Enter the number of the interval. Which interval is the narrowest? Enter the number of the interval. True of false: Assuming all the confidence intervals are made with the same data they will have the same center but different widths. Enter T for true or F for false.Question 5 1 pts Which two of the following could be confidence intervals with the same sample? O (0.45, 0.75) O (0.35,0.45) O (0.3, 0.6) O (0.4, 0.5) Question 6 1 pts (0.24, 0.56) is a confidence interval for the proportion of people who liked a new soda flavor. What was the sample proportion for those who did NOT like the new soda flavor? Type the exact answer as a decimal.Question 15 1 pts Find the upper limit of 90% confidence interval. An SRS of 185 students were taken from high schools in a particular state. 131 students responded yes when asked about if they felt ready for college. What is the upper limit of the interval approximation for the percent of students who feel ready in the population? Write as a decimal (not as a percent). So 0.8234 not 82.34% (if your answer was 0.8234)Question 8 1 pts (0.24, 0.56) is a confidence interval for the proportion of people who liked a new soda flavor. What was the sample proportion for those who liked the new soda flavor? Type the exact answer as a decimal
