need the ans for rest all. The price that watermelon farmers get for their watermelons has a normal distribution with unknown mean of dollars per hundred pounds and known standard deviation σ =$1.92 per hundred pounds. We wish to create a confidence interval for u. We randomly select 20 watermelon farmers and measure the price per hundred pounds x; that eachfarmer gets for his/her watermelons. The sample mean was x = $6.88 per hundred pounds of watermelon and the sample standard deviation was s = $1.37 per hundredpounds.a) What is the critical value for a 95% confidence interval for u?b) Create a 95% confidence interval for uc) How long is the 95% confidence interval for μ?d) How many observations would we need to guarantee that the 95% confidence interval above has a length of 0.8 or less?e) Create a 95% prediction interval for using this data.f) Assuming σ is not known, create a 95.0% confidence interval for using this data.g. What is the length of the confidence interval for part f?h) Copy your R script for the above into the text box here.

A student pursuing a degree in English as a second language believes the proportion female factory workers who can't speak English is less than the proportion of male factory workers who can't speak English. To test her claim she randomly selects 373 female factory workers and out of them 43 could not speak English. She then randomly selects 215 male factory workers and out of them 65 could not speak English. Test her claim at .=0.05 to see if she was right. The correct hypotheses are: H : PF Pu (claim) H : PF 2 PM HA: PF < Pr (claim) H : PF = PM HA: PF + PM (claim) Since the level of signficance s0.05 the critical value is-1.64s The test statistic is pound to 3 places) The pvalue is round to 3 places) The decision can be made to oreject H, odo not reject í, The final conclusion is that: There is enough evidence to reject the claim that the proportion female factory workers who can't speak English is less than the proportion of male factory workers who can't speak English.
