Using the normal approximation for the binomial distribution (without the continuity correction), what isthe test statistic (z-score) for this sample based on the sample proportion?z =(Report answer as a decimal accurate to 3 decimal places.)You are now ready to calculate the P-value for this sample.P-value =(Report answer as a decimal accurate to 4 decimal places.) In a certain school district, it was observed that 28% of the students in the element schools were classifiedas only children (no siblings). However, in the special program for talented and gifted children, 131 out of373 students are only children. The school district administrators want to know if the proportion of onlychildren in the special program is significantly different from the proportion for the school district. Test atthe a = 0.05 level of significance.What is the hypothesized population proportion for this test?P =(Report answer as a decimal accurate to 2 decimal places. Do not report using the percent symbol.)

Given that Sample size n =373 Favorable cases x =131 Sample proportion p^=x/n =131/373 =0.3512

B) what is the distribution by correct notations and related parameter values?( show work)
th A scientist studying babies born prematurely would like to obtain an estimate for the mean birth weight, µ, of babies born during the 24"" week of the gestation period. She plans to select a random sample of birth weights of such babies and use the mean of the sample to estimate u. Assuming that the population of th birth weights of babies born during the 24"" week has a standard deviation of 2.6 pounds, what is the minimum sample size needed for the scientist to be 95% confident that her estimate is within 0.5 pounds of µ? Carry your intermediate computations to at least three decimal places. Write your answer as a whole number (and make sure that it is the minimum whole number that satisfies the requirements).

Please help confirm I am correct: The mean number of push-ups performed in a cross-fit class in the population is u with a standard deviation of 6. Researchers are interested in whether a sample of 36 individuals in a new cross-fit class perform less push-ups than the population average. What is the probability that the mean number of push-ups performed by the sample of individuals in this new cross-fit class is 1 unit below the the population mean (or less)? I'm getting different answers- it is it 1, -1, .16 or .24? help! Thanks
