I want the answer for part a for the first question and for part b for the second question! The average height of children who are 2 years old is 34 inches. A random sample of 35 children who are 2 years old in a large daycare franchise is collected, and they are found to average28.00 inches with a sample standard deviation of s:1.80 inches. The researchers are suspicious that the children at the daycares are not growing as quickly as they should be.%3Dn USE SALT(a) Calculate the test statistic for the problem. (Round your answer to two decimal places.)t = -13.15t :%3Ds/Vn(b) Calculate the P-value. (Use SALT. Round your answer to four decimal places.)0.0000(c) Choose the appropriate conclusion for this test when a = 0.05.O Reject the null hypothesis.O Fail to reject the null hypothesis.O Reject the alternative hypothesis.O Accept the null hypothesis. The article "Well-Fed Crickets Bowl Maidens Over"t reported that female field crickets are attracted to males that have high chirp rates and hypothesized that chirp rate is related to nutritional status.The chirp rates for male field crickets were reported to vary around a mean of 60 chirps per second. To investigate whether chirp rate is related to nutritional status, investigators fed male crickets ahigh-protein diet for 8 days and then measured chirp rate. The mean chirp rate for the crickets on the high-protein diet was reported to be 107 chirps per second. Is this convincing evidence that themean chirp rate for crickets on a high-protein diet is greater than 60 (which would then imply an advantage in attracting the ladies)? Suppose that the sample size and sample standard deviation aren = 32 and s = 35. You can test the relevant hypotheses to answer this question. A significance level of a = 0.01 will be used.In USE SALT(a) State the null and alternative hypotheses.Ho: H = 60Hai u > 60O Ho: H =H: u + 6009 = 1 :ºHO Ho: u < 60Ha: H > 60O Ho: H = 60H3: u < 60%3D(b) Calculate the test statistic. (Round your answer to two decimal places.)t = 7.593t =s/Vn(c) Based on a = 0.01, what is the correct conclusion for the hypothesis test? (Use a table or SALT.)We would fail to reject the null hypothesis. This means on the basis of the evidence, you can conclude that the mean chirp rate for male field crickets that eat a high-protein diet isgreater than 60.We would reject the null hypothesis. This means on the basis of the evidence, you cannot conclude that the mean chirp rate for male field crickets that eat a high-protein diet is greaterthan 60.We would reject the null hypothesis. This means on the basis of the evidence, you can conclude that the mean chirp rate for male field crickets that eat a high-protein diet is greater than60.

Mr. Smith decides to organize a potluck party with neighbors on a weekend. John Smith and his wife Mary Smith and his daughter Judy Smith will prepare three different salad dishes. John's right side neighbor Jenny Jones and Bob Jones will prepare two desserts. John's left side neighbor Linda will prepare one meat dish. John's cross street neighbor Sue will prepare soup. John wants to figure out how many different ways for him to taste all dishes in order (assuming he will taste all salads, meat, desserts and soup). (Note : For example, "Salad, Soup, Salad, Meat, Dessert, Salad, Dessert" is one of the possible order he can try.

3. For this question, a = 100(n1 + n4) where n1 is the first digit of your student number and n4 is the fourth digit of your student number. For Halloween, Ambrosia collected a bag of candy. Ambrosia weighed her bag and found that there were a grams of candy in total. Ambrosia ate half her candy on the first day (the day after Halloween). Her father told her that if she continued to eat it at that rate the candy would only last one more day, so Ambrosia decided that each day she would only eat half of the weight of the candy left in the bag. She hypothesised that this would allow her to eat candy every day and never run out. Ambrosia decided it might be useful to use Mathematics to think about her remaining candy. She assigns t and W such that • t is a variable representing the number of days since Halloween. • W(t) represents the weight (in grams) of the remaining candy at the end of the day t. To understand what would be an appropriate mathematical model for this problem Ambrosia…
