This is the question im stuggling with To study peanut allergies in children, 320 babies who were at high risk for developing peanut allergies were given peanuts. 3.2% of these babies developed peanut allergies. How many babies in the study developed peanut allergies? This is what i did: i cross multiply x with 100 and 3.2 with 320 then divided both sides by 100 to get x=10.24. I dont think its right because to me it doesnt make any sense my question is where did i go wrong? How many babies did not develop peanut allergies?

You put n = 20 rats in a cage that is in a room with a 65-degree temperature. The next day you put them in a cage with a 70-degree temperature. On the final day of the study you put them in a cage with a 75-degree temperature. For each of the three days, you measure how many minutes of each hour they spent running on their exercise wheel. To compare the time they spent running on the wheel between the three different days (in other words, between the three different temperatures of 65, 70, and 75 degrees), what kind of hypothesis test should you do? One-Factor, Independent-Measures ANOVA One-Factor, Repeated-Measures ANOVA Correlation/Regression Chi-Square Goodness of Fit

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.
