**Stratified Sampling of Forest Areas in the Amazon Basin**Stratified samples are effective for studying large forest areas. In this study, satellite images revealed a forest area in the Amazon basin divided into 14 types. The focus was on four commercially valuable forest types: alluvial climax forests of quality levels 1, 2, and 3, and mature secondary forest. These areas were divided into parcels at random, with tree species counted in a specified rectangular area within each parcel. Here's the breakdown:| Forest Type | Parcels | Sample Size ||-------------|---------|-------------|| Climax 1 | 36 | || Climax 2 | 72 | || Climax 3 | 31 | || Secondary | 42 | |The goal is to select a stratified sample of \( n = 18 \) parcels. Address the following:(i). **Parcels to Sample from Each Stratum**:Determine how many parcels to sample from each forest type (stratum).(ii). **Random Sample Selection**:Utilize the following random digits to select a simple random sample of the size determined in part (i), within stratum Climax 1, without replacement. Explain how labels are assigned to parcels, and identify the selected parcels.Random Digits: 69051 64817 87174 09517 84534 06489 87201 97245This exercise demonstrates practical applications of stratified sampling, ensuring diverse representation across different forest types.

There are 4 strata namely Climax 1, Climax 2, Climax 3, Secondary. Each strata has units in parcels. Number of parcels in each stratum is known.Let Ni = size or number of parcels in ith stratum. N1 = 36, N2 = 72, N3 = 31, N4 = 42 N = Total population size = sum of the sizes of all strata = 36 + 72 + 31 + 42 = 181 n = sample size required = 18 given ni = size of the sample in ith stratum.(a). Allocation of sample sizes to each stratum is done with proportional allocation method. This method consists of allocating proportion of sample units equal to the proportion of the entire sample in the population that is niNi = nN this implies that ni = nN×Ni ni is not an integer then rounded to nearest integer. Climax 1: n1 = 18181×36 = 3.5801 ≅ 4 Climax 2: n2 = 18181×72 = 7.1602 ≅ 7 Climax 3: n3 = 18181×31 = 3.0829 ≅ 3 Secondary: n4 = 18181×42 = 4.1768 ≅ 4(b). In Climax 1, there are 36 parcels. First label each parcel with two digit numbers 01, 02, 03, - - - - - -so on 36 Select two random digits at a time from the list of digits starting from left to right. If the selected two digits represents number below or equal to 36 then select the corresponding labeled unit in to the sample. otherwise go to next two digits and so on. If the already selected digits are repeated then skip and go to next two digits selection. Repeat this procedure until n1 = 4 units are selected. The random digits are given as follows 69 05 16 48 17 87 17 40 95 17 84 53 40 64 89 87 20 19 72 45 Select parcels with labels 05, 16, 17, 20
